Crash upon 2-finger scrolling

Post by flow-c »

Hi!
Searching this forum (and the rest of the internet) led me to several reported bugs regarding 2-finger scrolling in guest OSes. My problem is different however and, as I believe, more severe!

My VB (v3.2.10, running on Snow Leopard 10.6.4) crashes whenever I attempt to scroll in either direction using a 2-finger swipe gesture. I reproducibly get the beach ball of death, and VB won't recover.
This happens regardless of the guest system(!), the problem even occurs when no guest is running, that is when I try to scroll in the VB main window!!
Secondary clicks in the form of two-finger taps are ok, as well as 4-finger gestures. 3-finger swipes, however, are a no-go too, but the hang doesn't occur as immediately as with 2-finger scrolls, it happens slightly delayed, say by 2 seconds!

Has anyone ever experienced something similar, or can you make a guess at what might cause this! It's quite annoying to get kicked out of a session just because one accidentally touched the trackpad with two fingers at once.

Looking forward to your replies,
flow-c

Make sure the guest additions are installed (in the guest) and turn off the absolute pointer in the guest settings of the VM. See if that helps.

Hi.
Thanks for your suggestions! The guest additions had already been installed. Unfortunately, disabling absolute pointer didn't help either.
Since the problem occurs VB wide, even outside the guest system, I really don't think that it has anything to do with the particular guest settings. Rather, it seems to be either a bug in the VB application or, possibly more likely, a faulty configuration of my system.

—SOLVED—
The problem was caused by a version of Multiclutch incompatible with Snow Leopard!
Removing the input manager it had installed solved the issue.
