When kwrite is started then the mouse wheel can be used to scroll up and down.
After a while (hours?) this stops working (nothing happens when using the mouse wheel).
Scrolling by other means (keys, scroll bar) continues to work fine. So does setting position and selecting using the mouse and clicking the mouse wheel continues to paste.
I have not been able to identify any specific event that causes it to stop responding.
If I open a new window/file from an instance of kwrite that has stopped responding to the mouse wheel this also does not respond.
If I start a new instance of kwrite then this will be fine (until it also gives up) so I can have responding and non-responding instances of kwrite running at the same time.
No other application shows this behaviour.
Using Xfce as window manager.
