Mouse Selection Goes Dead

Today I've encountered a bug (typically on leaving a building) in which my mouse's selection function stops working. The mouse itself is responsive, and the arrow even changes shapes when hovering near a target, although the coordinates seem to be off center. The keyboard works, but I'm unable to cmd-tab to the desktop or otherwise quit. I've also noticed random loading problems, e.g. low-resolution textures, looping ambient sounds. This began only today, but it's already annoying me a great deal.

Any insight would be most appreciated. And now I'm off to verify the game's files.

Specs: MacPro1,1 w/4GB RAM running OS X 10.6.5, CoH v. 1900.201011102104.27.

Does your Mac have ATI video?

There seems to be quite a few instability issues with CoH in general and ATI video (there are problems on the Windows version too).

Thank you for the input. I'll check my system logs if it happens again to see if I can pinpoint the problems better.

Even worse, my Mac just suffered a full-blown kernel panic in the middle of a solo fight in Praetoria (* edit: My first kernel panic in ages - I can't remember the last time it occurred):

I've already tracked down the cause of that kernel panic - fortunately it's very rare. It's caused by a runaway memory allocation that doesn't stop in response to errors, which eventually uses up all the memory handles and triggers a panic.

The only part I haven't figured out yet is what exactly triggers it.

Many thanks for all the research Macside on CoH. It's encouraging to learn that this bug is rare. Given the memory leak issue, I'm not surprised to learn this crash is also a memory management problem. I'll post further details if I run into anything unusual. Thank you again.
