Re: [Opie] Fwd: Unstable pointing?

Hi,

I've seen the same thing on my h2200. Sometimes pointer jumps to the top of
the screen. It makes handwriting recognition unusable. Sometimes when I'm
pressing a button in the GUI opie ignores it and I need to press twice.

Strange, but in GPE touchscreen works quite better. I've thought that GPE
and OPIE uses the same tslib, don't they ?

And even in GPE there is some jitter with touchscreen: when I drag scrollbar
and stop to move my stylus scrollbar positions still oscillates around
stylus. There is no such effect in WinCE.
