I haven't done the detailed testing like Guido but have been plagued by a similar problem with Stylepicker for a couple of years. Like Guido I haven't been able to find any logic in how Stylepicker behaves and it is different with different computers.

I cannot use the latest 2015 revisions because of this problem without messing about with LST/LS3 files

Come on PG, how difficult can it be to up the 20,000 limit? One line of code?
