I've got a couple questions for anyone who knows a bit about Xview:
1. When many Scrolling List calls are made in quick succession,
programs tend to dump core or otherwise go wild. Is there any
way of avoiding this short of putting delays between calls?
2. The documented Xview bugs (such as inablility to modify
the Scrolling List font, etc.) are getting in the way of
much work. Are there any patches/new versions of Xview, etc.
out there that I can use?
3. Is there any software anyone has to replace/imitate Scrolling
Lists that works better than the standard implementation?
Help in this area would be greatly appreciated! Thanx!

Brad, Set the font on the ***PANEL*** and the list will inherit it. Unfortunately so will any other panel item, so you may have to create other panels. I was told by Sun that they did it that way in XView, because the OPENLOOK spec requires items within a panel to have the same font; a requirement that I was also told may soon be relaxed. Frank G.
