i hope you guys will help me solving this annoying issue:
when i hover the mouse over the taskbar icons the preview of an open file pops up, but only a fraction of a second. normally the preview used to stay open as long as i point the cursor on it. as the preview vanishes immediately i cannot switch between open files anymore by using this taskbar preview feature. i recognized two more things that maybe belong to together with my dexcribed problem: the pop-up description of a file vanishes also too quickly. with pop-up description i mean that tiny box that shows up when i hover the mouse over it and contains the name or some information of the file. it vanishes also way too quickely than it did normally.
the other thing is when i open e.g. firefox, it is always in the background despite it is the activated application. with background i mean that i must always click into the window before i can type something in my google start page. some days ago when i opened firefox i could always start typing immediately without "activating" the window. and the funny thing is: when click on taskbar and hover over the icons the preview function works perfectly normal!
all these things used to work properly some days ago, but i needed to format c and reinstall win 7, now the preview feature isn't working properly anymore which is really strange...
i already looked for some online help but i could only find hints concerning how to enable or disable the previews or how to change mouse hover time before a pop-up displays. the solutions were always just simple clicks within the control panel or a change in the registry. maybe this issue is to solve as easy as these ones...
Thanks a lot!
