Sometimes my cursor switches to "Move Window" with
no reason, and my X server logfile shows "rxvt: timeout
on INCT selection paste".
I don't really know what triggers this behaviour (probably
some keyboard / button actions), but it's quite
embarassing because it locks X (I cannot focus on
anything or switch to another desktop), and I have to
kill it, meaning that I loose all my work.
I'm running rxvt-beta 2.7.10-0.1 (Debian Sarge package)
on an IBM Thinkpad T40 and I experience problems with
my mouse using X.
