Game crashes when ALT-TAB is pressed

#1 I keep seeing this come up and that it is 100% repeatable and yet I haven't seen it on any of my computers. If only everyone had the freaky machines that I have.

The ones from TGE in 2005 were related to the version OpenAL. You could try replacing the openal dll with a newer one.

But there were several people who couldn't get it to reproduce on their machines as well.

#2 I would be happy to send a build to GG immediately if they would take a look at it.

#3 Definitely, feel free to send it to me at:

mattl (at) garagegames (dot) com

I'll test it and see if it happens on my home machine or work machine.

#4 I had this problem with Grimm's. Bryce (my partner) found the bug in the engine and fixed it. There are a couple of similar bugs that you'll probably run across... and the portals WILL notice and make you fix them before you're allowed to launch.

Matt, Bryce doesn't come on these forums, but I'm sure he could provide you the source code if you emailed him: brycej (at) amaranthia (dot) com

#5 Thanks! Email sent.

#6 Just thought I would note that it did not crash on my machine here. I seem to have the "lucky machine".

#7 You must! :)

Crunch Time crashed on every test machine at VMC Game Labs plus all of our dev and internal machines (at least 6)...does Crunch Time doesn't crash on you when you go from fullscreen to the desktop using ALT-TAB?

(ALT-ENTER is the keybind for fullscreen).

#8 Yeah, you're probably not running on an old clunker like I am. Yarks! I bought my machine three years ago and it's already outdated.

#9 Just some data on the machines we tested on...

#10 Nope. That's exactly what I did. It took a bit of time for it to switch, but it did not crash. I've been doing that every time I see a message about this. I haven't had it do it on this machine (Compaq DC7700 or on my Dell e510). Neither machine is that great. I haven't tried on my Tablet PC or goofy Vaio.

I keep hearing about them and that they happen 100% of the time...but I'm here to prove that it is really 99%, I guess. Not that I have any idea what I'm doing differently.

I was hoping Amanda and crew's code had been implemented and it would stop showing up.

#11 Yeah, if Bryce could provide some source, it might help the GG guys locate some edge case that isn't appearing on their machines.

#12 Email sent to David.

#13 And forwarded on!

#14 So there was a solution for this problem?

I'm having it with 1.7.3....

#15 I would love to know if there is a solution too...I never found one.

#16 Im not really experiencing that... but if that's happening to that many folks, the problem does exist.

what im experiencing from my own project is that wheneve i switch form windowed to FS, the pause menu pops up... and am not really sure how to avoid that from happening ... is like the game is loosing focus when i switch to FS, but it shouldnt (theoretically, that is).

#17 This thread has some great info which fixed the problem for me. You need to recompile the engine using the source, but at least it works. Also fixed some other related bugs that were failing Portal verifications.

#18 I'm wondering if its an OpenGL/D3D issue. Did you ever try switching your display driver option in preferences? I used to have that problem when I was programming DirectX stuff. The program loses focus of the display driver and never gets it back. If switching drivers works, I'll take a look at the source and see if I can't find the problem. Been awhile since I last really used DirectX, but can't hurt to try. I bought the source for a reason=)
