I think that's by design, though. If it worked differently in 9.1 to now the change may be on purpose. I might be wrong, of course!
If you think it should be changed back, drop GPSoft a note and see what they think.
I can see arguments for it working both ways so I don't see either as being "right" but, equally, I'd find either way acceptable so I wouldn't mind if it was changed.
In case it's useful, here's another thread I found on this issue, where there's a command that can be used to launch the selected exe file(s) elevated (without prompting if already in admin mode):
[ul][li]Lister in Admin Mode, programs not elevated[/li][/ul]That command could be used on a button or bound to, say, alt-double-click on exe files.
