Hi guys, this may be my first post here, but I assure you, it's legit. I've been having the same problem, which has rather interfered with my quest to complete all missions of all games in the series in Hard Mode (where available). It turns out, the problem is to do with the refresh rate of Win 7. This explains why minimising and then maximising again the game window causes the menus to show up again.
The solution is to create a dummy second screen, even if you don't actually have one. By running the game from a fake second screen, extended onto the first, it works. I also hear this solution works for problems with Red Alert 2 on TFD on Win 7. http://img4.imageshack.us/img4/7223/tutorialcopy.jpg Note that this originally came from the C&C forums, here: http://www.commandandconquer.com/forums/showthread.php?1600-DX-problems-with-ra2-yr-and-tsun-on-Windows-7 (the second last post by user Weiss specifically). It's the only confirmed solution I've found that doesn't involve a virtual machine. I'm using an Asus N55F with Win 7 64 bit, the direct x solution didn't work and I can't disable Direct Draw on it.
One last thing - this solution works for both the standard TFD installation of the game, and the direct installation package that's pre-patched for Win 7 play.
Hope this helps people experiencing the same problem as me!
