Thanks. Hum? I'm setting the label and I'm returning a handled =
true in a popSlect event, but the problem still persists. Any
further ideas where I could be going wrong here.
I was using LstGetSelection(LIstType *listP) and I thought this might
be causing the problem. However, I still get the error when I set
everything manually and try selecting from the drawn list.
