I Alt-Tab a lot, and I've noticed some weird behavior. Basically, it becomes a lot slower if I do it too quickly. Ordinarily, Alt-Tabbing to another window from CoH will be instant. However, if I then go back to the game and Alt-Tab after only a few seconds, my computer freezes up for a few moments before the window changes. It's usually less than a second, and I can still move the cursor (which changes to the Windows cursor, and I can move it). If it takes a long time to switch over I can even force it to switch by hitting Ctrl+Alt+Delete, then cancelling out of that screen, but it's usually not necessary. But anyway, yeah, game starts being reluctant to lose focus if I Alt-Tab too frequently. Anyone else experience that?
