Crash and Reboot after quiting?

BlitzMax Forums/BlitzMax Programming/Crash and Reboot after quiting?

Amon	(Posted 2007) [#1]

I'm using the latest Bmax, latest syncmods, WinXP PRO SP2, latest 100. Nividia 7950 GX2 graphics drivers, 4GB Ram - 3GB Useable.

I'm also using BLide as my IDE.

Using the code below whenever I exit the app by pressing escape, half the top corner of the screen goes black and then my PC Reboots.

I'm not a technician or an experianced coder so don't exactly know what is causing it.

Include "ExampleTiming.bmx"

Are you fireing timer events in "ExampleTiming.bmx", I dont think that would nessesaraly do what you say, but without the include..... who can tell

There are no timer events in ExampleTiming. I can say for sure it wouldn't cause the PC to crash :-)

My laptop sometimes hangs when I exit GL apps.

Try running it under DX instead.

Amon, if you take out the include and all the associated command does the problem still occur?
If so, you could post that code for people to try.

I've removed the include and I still get a crash when exiting so it can't be the ExampleTiming. ExampleTiming is part of Greys Framework. It handles the fixedrate Logic.

I took GFK's advice and switched to DX and don't get any crashes so this is definately a driver issue.

I'll do some more tests and post my results.
