Okay (different people have complained about the same thing, so I take it
as it is not just your machine.).

This is not an excuse for not the reseting it. (I often want(ed) to test
ps2 in compare to how synps2 behaved)

ps.
I am going to look futher into the code as I just experiented something
funny after starting and stopping the synaptics. The keyboard updates
slower and the mouse/cursor jitters when I press some keys.
