But although single-click works on icons in the Panel, it doesn't work for desktop icons that are 'links to applications', e.g. Konqueror opening some directory.
Mmm. That was on Mageia-2 on the laptop. I've now installed Trinity on the Mageia-2 on my desktop, and that problem is not occurring.
Both Mageia-2 installs were from the same .iso, but on the laptop I had not done a s/w update before the Trinity install. Could that have caused the problem? Anyting else I could try?
