[UI] Scrolling issue

[Adrian Lienhard]

Hi,

I've been using UIEnhancements for some time now. I like the look and  
many of the features but one thing that is annoying is that the  
scrolling behavior is broken (I'm on Mac OS X, Squeak VM  
3.8.18beta1U). The behavior is that scrolling the list does not stop  
when you stop scrolling the mouse or trackpad. It looks like the  
scroll events are queued up and processed up until the last one while  
each step takes a lot processing time. The problem is that while it is  
scrolling the UI is unresponsive.
The old behavior was that scrolling fast would also scroll the list  
fast while now the speed does not seem to differ.

Cheers,
Adrian
