It seems that Sun in it's Xview stuff must have the process group set, or some such nonsense. All of our GUIDE stuff which generates Xview code has the same problem. If I run 'xterm' I don't have this problem. Who knows if Sun will ever make X things work in nice conjunction with MIT X, I say this because I notice this when I use XDM. Best solution is to just use xterm it is a better utility anyway. I mean at least you can do file completion in a scrollable window. Come on Sun this bug is so old the cost of formaldehyde needed to keep it there must be phenomenal. -- | () () () | Frank P.
