I tried the dictionary and it did not seem to cause the same symptom as 
described. I noticed that the file dialog box hangs sometimes and brings 
my cpu speed up to maximum. The file chooser eventually gets to the save 
to folder portion. It does so very slowly though.

Since this is a laptop and does not get prelinked regularly and there 
are constant rpms being upgraded, I'll check if the problem might be 
related to a "half and half" optimization. I am guessing here.
