David gave you an answer that works for downloading, but there could be other events you want to "wait while"
Suggestion: try a custom property wait while the cpBusyFlag of this stack is not empty --since it might trigger when a script local will not -- seems like a bug to me Another thought is to do the following to force the re-evaluation of the flag variable get lCurrentFileStatus repeat while it is not empty get lCurrentFileStatus wait 1 second with messages end repeat Hope this helps Jim Ault Las Vegas --- Andre Garzia <[EMAIL PROTECTED]> wrote: > Hello Friends, > tricky newbie question here.
