Description Vlado Potisk 2009-05-13 00:03:36 UTC
Version:            (using KDE 4.2.2)
OS:                Linux
Installed from:    Fedora RPMs

I'm developing an application using the xterm mouse tracking. I have encountered a problem with mouse button doubleclicks.

A left button doubleclick is reported normally as 2 clicks, i.e. 4 events:
- button 1 click
- release
- button 1 click
- release
but the right button doubleclick is in most cases reported only as 3 events:
- button 3 click
- release
- release
The second click of a doubleclick is not reported in about 7 out of 8 tries. In my opionion that is incorrect.

The xterm does not have this problem, it always reports all 4 events of a doubleclick.

Can you reproduce on a later version?  4.5.x or 4.6
Comment 2 Vlado Potisk 2011-03-04 20:11:45 UTC
Yes, I can reproduce it on konsole from KDE 4.5.5 (Fedora 14, x86_64)

I believe I may be also experiencing the same problem.  I too am using Fedora 14, x86_64, KDE 4.5.5.  I tend to do lots of double-click to select, middle-click to paste operations and about half the time the middle-click pastes nothing.

My first thought was I'd worn out my mouse.  Replacing it with a new one got me the exact same results.  It wasn't until I started paying closer attention that I realized it was only konsole that was affected.  All other apps are fine.

It seems to help somewhat, to pause a second or two between the double-click and the middle-click, but it's difficult to change an established habit.
