Fix scrolling in GTK apps (Pidgin) on Windows

Synaptics makes great touch technology. Their performance and drivers have always been, in my experience, much better than their Alps counterparts.

Except in one specific situation: using the trackpad’s edge scrolling feature in Pidgin.

Turns out the problem is because the Synaptics touchpad enhancer app displays a custom cursor while scrolling in such a way that prevents GTK apps from reading the scrolling action. Not sure on what end the bug is, but the good news is there’s a simple registry fix:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPEnh]
"UseScrollCursor"=dword:00000000

Either copy-paste the above into Notepad and save as “DisableSynTPCursor-FixScrollPidgin.reg” or something less complex, and import it into the registry. Or make the change manually.
