On the crash popup, you have not a small link on bottom "view problem details" ?
No. Just "Close Program" and "Wait for Program to Respond"
I believe that mGalaxy is not crashing...but simply waiting for Mame to quit!!
When you quit a game, and that mGalaxy seems crashing, call the "task manager" and check to see if you can find an occurrence of mame running or not!
When this happens, Task Manager is not able to be seen. ALT+TAB stops working. I can select Task Manager with ALT+TAB, or any other application, but it won't switch out of mGalaxy.
Whatever is happening, it's definitely a combination of mGalaxy and MAME.
If I cause the mGalaxy "freeze" to happen, I was able to shutdown MAME via ALT+TAB. This allowed mGalaxy's menu screen to come back and mGalaxy was functioning again.
The problem is, if I run MAME by itself outside of mGalaxy, I can exit a game at any point and instantly get back to the MAME menu screen.
When you add mGalaxy, it doesn't work if you do it too quickly. Everything points to mGalaxy having a problem in this specific scenario, almost like it's frozen and preventing MAME from exiting.
