I have just solved a strange problem,and would like to offer the solution to others, and ask if anyone else hase seen this. I am running XP with 2 monitors. I noticed that after swapping my secondary monitor (and changing its resolution), the sub-catagories in the Liraries Palette would not have an arrow at the bottom for scrolling down. I found that the position of the bottom scroll arrow seems to be determined by the largest screen resolution of all active monitors. I disabled the secondary display (right click desktop), and now I have the bottom scroll arrow again. Anyone else had this problem?
