Hi All, 

I have problem with Synaptics touchpad on Dell 640m(E1405)
and Lenny. From several days very oftten touchpad arrea and
buttons stop responding, after a minute they are back 
functional. If I press keyboard key (any key) during hang 
period touchpad function properly.

Google do not help me. Any advise will be appreciated.
