move_end not supported

[jcartledge]

fingerpoken crashes as soon as I try to swipe on the touchpad. This is 100% reproducible on an iPhone 3GS running 4.2.1 and an iPad also running 4.2.1.

I'm running the fingerpoken-0.2.20101217123250 gem in Ubuntu 10.10 under RVM ruby 1.9.2:

jcartledge@HAGAR ~> ruby -v
ruby 1.9.2p136 (2010-12-25 revision 30365) [i686-linux]

Here's the stacktrace:

Sorry about the problem. I'll try to reproduce and get a fix out shortly!

[jcartledge]

Thanks! Happy to provide any info you need.

[jordansissel]

ahh, reproducible. I'm working on a fix.

[jordansissel]

Version 0.2.20101227000817 should fix your problems - they were already fixed in master, and I took this opportunity to fix up a bunch of other issues before pushing a new gem; ready now!

Can you test and confirm?

[jcartledge]

All good here. Thanks for your prompt response, I'm really impressed!
