More seriously.. :) One thing that has nagged at me for a little while, is could it be swap-related? I have 3 or 4 major apps each using >1/3 of the physical memory (1 GB). What if some of the memory used by LyX gets swapped out due to disuse, and the act of resizing triggers LyX/Qt to inspect much of this and so the pages get swapped in? It could possibly explain why LyX gets slower and slower except I don't see why pages should get swapped out of an app that's being actively used. Unless something else is misbehaving. (I blame Firefox which idles at 10% CPU when no part of it is being displayed.) Also, I don't notice the usual pause and disc activity that would indicate swapping when LyX is in use. The fact that I can scroll over the same page of text again and again and see that it is too slow would hopefully rule out a swap issue. When I have zero swap in use, I'll verify the problem is still as described. Have fun, Darren
