Usually I open a forum in the browser, and right click the message I want to read and select
"open in new tab". Just recently, instead of the right-click menu appearing and allowing me to
select what I want, the menu flashes up and disappears. I try it a few more times and eventually
it stays on the screen. It's happening in both Konqueror and Firefox.
Any thoughts on this? My first impressions are that it's something to do with the mouse
or perhaps the video driver. I've got dual boot Windows on the box and it's not happening there.
TIA for any suggestions.
EDIT this problem cleared up after installing the KDE 452 update.
