Tablet features stop working, X61 Tablet, Vista SP1

[gpvillamil]

Very annoying issue here - while working intensively with the tablet features, eventually pen and touch input stops working completely. Fortunately, the TrackPoint still works, so it is possible to save work and continue.

I remember this being an issue with Windows XP, but I thought it had been fixed under Vista?

Also remember that there was a fix, killing either the tabtip.exe process or the wisptis.exe process and relaunching it.

Anyone remember what it was? Thanks!
