I think it is since the last update 9.4 that in some cases programs just opened don´t come in front of other windows. Until now I cannot say under which circumstances. For example I open "reedit" in the search field and it shows only the button in the taskbar. More often dialog windows don´t come to front, especially in connection with ptinting. The Epson print prewiew is often not visiible or the file dialog when I print to PDF. What could cause this?

Hello Owen, it was already set in my configuration. But I tried to disable and anable it again with no success. But I have another program called MemoMaster which I suspect to cause this behaviour. In this program itself I looses often the focus. After a restart of the computer all is normal until I start that program. I´m in a long discussion with the maker of this very good database software. It causes also that I can not see floating windows inside programs like Photoshop, AutoCAD or 3dsMAX when I switch back from MemoMaster. I need to cklick on the titlebar once to get the floating windows back. The programmer said they cant change it due to some restrictions to the Windows software itself.

This happens also when Display Fusion is of. I tested it just now once more. It doesn´t happen every time, but in the last case I had the MemoMaster in front of the middle screen and behind this an AutoCAD window. When I closed MemoMaster AutoCAD was shown without the floating windows. I have to click on the taslbar once to get it back.
