Touchpad hungs when scrolling in Firefox (M6500)

Hi,

I'm a happy user of Dell M6500 mobile workstation. However there is one thing that drives me crazy. It is touchpad software. I'm using the latest version 15.1.6.2. When I try scrolling with a trouchpad scroll area when in Firefox my mouse coursor freezes, CPU load is 25% (single core fully occupied) and I need to kill SynTPEnh.exe process in order to restore cursor movement. I'm using Win7 Ultimate x64.

Does anyone have any clue how to prevent this?

Thanks and Regards, Marcin
