Hello,
First of all, thank you guys for the wonderful program. I guess I found a bug regarding the advanced search. After I tried to search for a math expression several times, when I clicked the advanced search button, it pops up an empty window. Also, when I first open LyX and recall the advanced search, it pops up a very small window. So I need to enlarge it manually. After enlarging it, there is a small glitch (I think) in the UI. I attach screen shots for the above problems. Cheers, JM
