DirectDraw applications Freeze on Windows 7 anywhere between 1 minute and 3 hours into running them.

Scouring the web, I have come to the conclusion that this is a Windows 7 issue, and there is no link between hardware, or drivers as it occurs on ATI, Intel and Nvidia chips.

Games such as Starcraft may freeze as soon as you hit the first menu screen, or as late as half way through a mission.

Age of Empires * games freeze on a black screen between the last intro video and the main menu (but as tested so far once in a mission will not freeze)

Warcraft 2 BNE is the same as Starcraft.

Worms Armageddon is effected randomly as well.

Heroes of might and magic 1 and 2

Starlancer (between missions or on he main menu)

Blood Omen during during movie sequences

So far i've verified that

Affinity does not fix it.

Process Priority does not fix it.

End tasking or pausing Explorer does not fix it.

Selective startup does not fix it.

Running without drivers will not fix it (don't even bother suggesting it).

This is an issue that doesn't have any correlation to system configuration,  The game that gets the most coverage with this issue is Starcraft and though that might get a Patch, its no doubt that the Age of empires games won't.

The freeze is not a hardlock,  rather its a freeze of the display and input controls.  Processes in the background continue running and if you are in a chat on skype or xfire these continue as well according to some users.

Someone mentioned a Race issue between Ddraw and WDDM, but i've no idea how to verify that.

Specific Starcraft issue is here http://www.sevenforums.com/gaming/11659-starcraft-freezes-after-1-5-minutes-playing.html

Note:  All the fixes known to work on Vista, do not work on Windows 7.

This issue only occurs in games that also have the bad colours issue, so basically any 8bit/256 colour titles. 16bpp appear to be fine.
