Mac os 10.5.8

Any ideas on how to fix?

[Pyro]

When did this start happening? Same computer I take it?

[Zaknafein]

yes

[Zaknafein]

After the game ends, sometimes myth will disappear entirely and I will have to force quit to reopen it.

Why are you still using Leopard? Upgrade to Snow Leopard.

[Zaknafein]

When did this start happening?

Sorry didn't see this part. It started happening a couple days ago.

Did anything change that could have caused this? Perhaps you updated, installed, or uninstalled something? Do you leave your computer on for multiple days? If so, you could try restarting and see if that helps.

Do you play other games on that computer? If so, do any graphics related issues occur? Could it be overheating and therefore causing trouble to the graphics card?

I've seen oddities within the preference files in the past, you could try renaming your preferences folder (to keep it as a backup) and start up Myth. Set everything to how you had it before and see if that changes anything.
