Bugs and Other Misbehavior
How do I report a bug in
First: X-Plane is a complex piece of
software with a pretty big learning curve and some non-obvious
Unless you're an old-timer and are really up to speed on how it works,
ask the folks on the tech list first. It's just possible that you're
misunderstanding something or X-Plane just works different than what
That said, if the folks on the tech list say it's a bug, or if you
just know it's a bug, use the official X-Plane
freezes almost immediately after startup (V9.20-9.21)
The cockpit view is displayed but there
is an approximately 30 second delay in response to any keystrokes or
mouse clicks. This occurs if your computer is connected to a network
but the network does not have connectivity to the internet (for
example, a private LAN). X-Plane is attempting to check with
X-Plane.com on the available of updates. If the network connection
can't be established it freezes until it gets a response. The solution
is to disconnect the computer from the network entirely, causing the
network connection attempt to fail immediately. There is no solution
for running networked copies of X-Plane on a private LAN.
My computer crashes or freezes
while X-Plane is starting up
This problem is almost always caused by
buggy video drivers. X-Plane is a user-mode application and by itself
is not capable of crashing the system. Contact either the manufacturer
of your computer system or video card for up to date drivers.
There is a large square of land
in the Mediterranean
Located immediately northeast of
Zuwarah, off the coast of Libya.
This is a defective scenery tile. Fortunately, the area in question
should be open ocean. Just delete the offending scenery file:
Global Scenery/-global terrain-/+030+010/+033+012.dsf
(If you originally installed from the old V9 beta kit, you'll find your
global scenery in the Custom Scenery folder, rather than Global
Scenery.) There is a corresponding file in the -global overlays-
folder, but it's empty and is harmless.
X-Plane (or the entire system)
crashes after I've been flying a few minutes
There have been a couple of cases
reported where this problem is caused by sudden heat buildup. X-Plane
runs your cpu and video card at maximum performance, which generates
more heat than other forms of system use (word processing, surfing the
When I try to start X-Plane on Windows, I get
the error "Missing export DSOUND.DLL:11".
You need to install DirectX 8.1 or later.
What is an unhandled exception in X-Plane and
how do I fix it?
An unhandled exception is exactly that..
an error (exception) that was not trapped (handled) by the software.

error number that occured. The second is address and points to the
memory address in the code segment of the program where the exception

know how to find your way around a debugger to trace the problem.

in X-Plane that resulted in this exception.
X-Plane crashes or hangs the system when I
This is usually a problem with your
OpenGL or video drivers. Make sure your drivers are up to date. In some
instances you can work around this problem by manually setting your
screen resolution to the resolution X-Plane will run in before starting
Suddenly the sound has
stopped working in X-Plane (Macintosh)
This can happen if you use Audacity (a
Macintosh sound editor). Audacity changes all the sound sample rates
and other apps stop working. You need to run
Applications/Utilities/Audio MIDI Setup and reset the sound sample
rates to the default 44.1KHz. For details, see the discussion
Problems in older
I see no scenery on Mars (version 7.50)
This was a bug in 7.50; it's fixed in
7.61 and later versions.
When I cross a waypoint set up in the FMS,
X-Plane 7.30 crashes
This is a known bug in version 7.30. If you have the
autopilot slaved to the FMS (i.e., LNAV mode) X-Plane will hang,
typically with a terrible noise in the audio) when you get within .3 to
.5 miles of the waypoint. This problem is fixed in 7.41 and later. If
you want to stick with 7.30, to circumvent the problem, when you're
within 1.5 miles of the waypoint, manually advance to the next
(Thanx to Andrew Bright for the workaround.)
My joystick doesn't work under Mac OS 10.3!
Apple screwed up USB HID support in a serious way in 10.3.
Get the current 10.3 update - the joystick problems were fixed in
7.30 and later won't start on my iBook with 8MB
The increased panel size in 7.30 pushed VRAM requirements
over the edge for Mac iBooks with 8MB VRAM and running OSX. It still
works if you're running OS9, which uses slightly less VRAM for the same
application load. (But it probably won't for long).
I can't edit obstacles in WorldMaker 7.21!
Neither can anyone else. It's busted. You'll have to use a
I'm on the US west
coast. Why does the GPS show Japan to the east?
Not anymore it doesn't!! (If you have 6.06 or later.)
In 5.66... Because X-Plane thinks the earth is a flat rectangle.
The world ends at the international date line west of Hawaii and east
Japan and New Zealand.
