Every now and then, I find that the shift key gets "stuck on" in DOSBox. For example, typing on the command line will result in text in ALL CAPS and playing Civ2 in Windows 3.1 will cause "shifted" shortcuts to get executed when I hit the letter on its own, and vice-versa (eg. T brings up the tax rate screen, shift+T shows hidden terrain). Why is this happening and is it a known bug? I can't identify when it starts happening... it seems to be at random.
