JCL: Then it's not likely to be a DEP problem, since we're not exactly in the habit of releasing games (even betas) that requires development environments. However, I'll have the user check his DEP settings anyway, just to verify that DEP's not the cause.

Is there any reason to believe upgrading to 7.07 and re-releasing a new beta version of our game to hundreds of beta testers will actually solve this problem? (It's a lot of work affecting a lot of people to do this and could introduce new bugs as a result of migration, so I'd just like to know it's not just a stab in the dark before we do it.)

Thanks.
