I think so, for each method view there is an SHTextStyler / SHTextStylerST80 
which
computes the colors for styling in a background process. At least that part of 
your
problem is coherent. 

Though I still have no idea why the styler would fail and hang the process, so 
far 
I never experienced that. I suspect some "strange" mehtod / source code must 
trigger
some bugs in the styler?
