Yay. I love not being able to pause most of the time; it's great when the phone rings and I have to leave my battle running. And watching my army being massacred on the highest speed setting while I frantically punch ctrl+t over and over trying to get it to slow back down is great too! Serves me right for trying to speed past the opening phase where my army marches in a mostly straight line, doing not much, in a bid to actually play more of the interesting parts of the game.
That's a not a bug, but rather a lack of video memory. You try cramming 2000 individually-rendered troops into a battle and then see how well your video card works when the game speed is at maximum and the game is trying to catch up on rendering each frame by frame.
Upgrade your memory and/or video card, or play with lower unit-size settings.
