[NCLUG] Mouse Sticks to Widgets After Upgrade to RH 7.3

 How much RAM and swap do you have on this machine and how heavily utilized
is it (use 'top')? I can't speak to either the quality or size of KDE but
low memory and a (comparitively) slow CPU can sometimes show up like this.

 Lines in 'top' that you'll want to look for (using my work machine as an
example):

CPU states:  0.7% user,  1.9% system,  0.0% nice, 97.2% idle

 Obvious. If the system is 0% idle it's very busy.

Mem:   512372K av,  507776K used,    4596K free,     680K shrd,   68200K buff
Swap: 1052216K av,  291648K used,  760568K free                  238536K cached

 It's no fun when the used Mem approaches 0 (generally I've seen 3MB free
on heavily swapping systems).

 Down in the per-proccess area:

 2367 root       9   0  123M  22M  8596 S     1.5  4.5  3790m X

 Yes, the X server can get large.

 2370 mloseke    9   0  1532 1380  1168 S     0.1  0.2   0:17 fvwm2

 My window manager, most others are much larger. Since KDE is an
"environment" there will be several child processes doing different things
but it's a place to start looking.

 Hope that helps.
