The game will load and launch fine but after a few seconds the display freezes. I can hear sounds of the game progressing but nothing changes on the screen. If I minimize the game then bring it back up then I can see that units have moved but the screen is still locked showing the units where they moved to.
I've tried various screen resolutions, windowed mode, and rendering modes but the problem persists in various forms. So far the least problematic settings are:
Resolution: 1366x768
Rendering: IE-ddraw
There's also this weird click sound, not like a mouse click, that happens when building units.
I'm having a similar problem with Tiberian Dawn. One mission will run fine but during the next mission i cannot use the menu at all. As soon as I hit esc key the mouse freezes and I can't see where I'm clicking. Alt-tabbing shows the mouse where it should be but it's still frozen.
