I bought MSTS yesterday and I installed and played it. I closed it to eat dinner and came back to play and I got in the game and loaded up a mission only to find out the keyboard no longer works! The only way to get out of the game is to Ctrl+Alt+Delete out of it, when task manager comes up I saw the CPU usage read 100%.
My system is....
Pentium 4 2.2GHz
256MB ATI Radeon 9250.
1GB RAM
I have MSTS installed on my 250GB external HD. I know it's not the HD because I have FSX, BF1942, SWBF2, Lego Star Wars 2, LOMAC, JetFighter 2015, MX vs. ATV, SC4, and Civilization IV on the HD and they work flawlessly.
