Kept getting disconnected remotely -- plus the mouse seemed unresponsive:
I use a logitech mouse(marble trackball). In system tray software you may want to try check/uncheck of use 'os' vs. 'trackball' implementation for speed. Likewise, if you have this running on desktop from which you initiate logmein -- you may want to consider turn it off/exit on remote pc.
These things seem to have helped.
