Explaining is quite hard, even if my English is not well. Well so; after quitting an application generally we can skip to another open window(task) by Alt+Tab keys easily but sometimes, after quitting some applications this is impossible without, either before minimizing all applications by WinKey+M or clicking to any window(desktop also) by mouse. I mean, Alt+Tab keys doesn't do the job, even there is other open tasks. Of course I'm talking about managing windows only via keyboard. Let me give an example, a lot of Borland Tasm applications do this for me, as I noticed. Maybe this is a long explanation but don't know can I explain this shorter. This time my Dev-C++ application does the same thing. Hope I could explained sufficiently. Anybody know a solution for this situation. Or how can I research this in the web? Key words? I do not need to explain why this is a problem for me, can understand this somebody who feels the same.
