QT problem or KDE?

First- thanks for your great work!

I have downloaded and installed the binaries you provided, and they 
work ok (although very very slow).
However, I did notice that when working with Hebrew text, I have many 
problems (selecting problems, problems with text insertion point etc.) 
that I do not have in the Linux version of KDE.

I wonder where did these problems come from- does the Qt/Mac have 
different i18n support then the linux version? Is it something in these 
builds?

Any ideas?
