Hey guys, really sorry for the late reply! It's quite a while ago I've been the last time on here...
That is definitely possible. I needed hours to make it stick, lol.
If you have Visual Studio C++ Express and a little knowledge about the language you can easily disable it, I think. Just delete the order-setting functions.
Unfortunately I noticed that too afterwards and couldn't find a fix :/
The problem is I used Threading for this because else the drawing would have stopped the game while drawing.
GM seems not to like Threads though. It's not that the Thread is not quitted properly, I think, so the issue has to be somewhere related to GM... The issue appears only when quitting the game, right?
Wish I had more C++ knowledge to solve this... The method I used for synchronizing the Threads might be the issue.
