**System Information**
Lenovo thinkpad E520 (Edge laptop)
Windows 7 sp1
Graphics card: Intel HD Graphics 3000
**Blender Version**
Broken in: 2.72b 9e963ae. Tested 2.72 (initial release) & is also broken.
Worked: (optional)
Confirmed that it currently works in 2.71, 2.70a, 2.69 and 2.68a on the same laptop.
**Short description of error**
Scrolling panels (e.g. Properties Panel) with touchpad gesture (simulated Mouse wheel) does not work (no movement).
Zooming using the the same touchpad gesture does not work. It will intermittently zoom in a small amount then stop working
Note that I can still scroll by grabbing the scroll bars and I can zoom with Ctrl-middlebutton without problems.
**Exact steps for others to reproduce the error**
On Thinkpad E520 laptop make sure touchpad is set up with the mouse wheel gesture (for me it is a two-finger swipe down or up).
Run blender 2.72, or 2.72b .. Go to 3d View then attempt to zoom with "mouse wheel" gesture.
Go to Properties panel; adjust size to make scroll bar appear; Use "mouse wheel" gesture.
