Somebody has already mentioned that TD 2.0 isn't compatible with Windows Vista (which includes Internet Explorer v7 as standard). Actually TD2 doesn't appear to work properly on XPSP2 with IE7 either.
When I open up the program, a pop-up window is displayed, but its empty and I can't read the contents. This also occurs every other time a pop-up window appears. TD2 also crashes when I open the 'Sounds' tab.
If anyone knows a workaround for these issues (that doesn't involve uninstalling IE7) let me know. Corey, if you want to download the beta of IE7 to test these problems yourself, you can go to
