Thanks, this is certainly part of the problem, although I wouldn't lose any sleep if it didn't get addressed. According to our engineering guys, the problem is that they can't interrupt their application at all using Ctrl-C (this application in turn calls patchadd). So we were wondering if there is something in SMF which disables interrupts when legacy apps are run? Thx, Trev -------------- next part -------------- A non-text attachment was scrubbed...
