Using TrackPoint freezes Touchpad for a second

[tomino]

I experience a problem on my T60 1951 F5G on Windows 7 with TrackPoint and its buttons. I use TouchPad most of the time with my right hand, but for me its comfortable using TrackPoint buttons with my left hand, as they are easily accesible - untill now.

Problem came with new version of UltraNav driver (15.1.19.0 dated 14 oct 2010). Touchpad area stops responding for approx 1 second by clicking any TrackPoint button (or by using TrackPoint itself). I haven't found any topics related this issue on windows 7. Have tried to look into UltraNav documentation to find any clues or settings to solve my problem with no results. It seems the freeze time is constant.

Please help.

I have also noticed in this version of UltraNav driver (previous version too), that process Synaptics TouchPad Enhancements made too many page faults (approx 1 milion in just two hours) - is this standard behaviour? More pagefaults has only Desktop Windows Manager.

Thank you very much for any help.
