After a certain period of time of having certain programs (including Notepad++ and Inkscape among others) open, coming back to and clicking anywhere in that window causes it to immediately minimise, as though I'd clicked on the window that is actually behind it. Using a keyboard shortcut to bring up a Save As box lets me interact with that box but as soon as it's gone, I continue to have the problem and the only solution is to close the program and re-open it again. The time needed for the program to be open seems to vary from 30 minutes to several hours. It has not happened whilst I've been actively using one of the programs but when I've used some other windows and come back to it.

Does anyone else recognise this problem?
