That was the problem! Thank you very much! I now have disabled the System setting "closeWindowOnMiddleClick" and everything works as it should.You might reconsider your choice of function for the middle button. The KDE/Gnome method of cutting and pasting between apps is the middle mouse button. Ctrl C, Ctrl X and Ctrl V work within apps on content moved within those apps, but I've found that between most apps you must use the middle button.... and past it with the middle button.This I can not do as I have set the middlebutton for "close" window. But
it should nevertheless work with ctrl+v - but it does not.
Well, I think I can get used to alt+F4 again...
By the way, try running klipper. Doing so often improves your cut and paste experience.Thanks for the tip. I am now just fine with the basic copy-paste function and have other tasks/problems to handle with - with lyx (I am going to post some more soon).
Best wishes,
