I also don't have problems displaying a floating wait window in similar
circumstances. Perhaps something's happening as a result of your OnChange
event that's changing the TreeView? You need to ensure the TreeView is not
modified during the OnChange.
Cheers,
Carl

We use standard TTreeviews and do processing that causes focus changes and
window displays
during the onChange. This is not the cause of your problem. We will likely
need more detail or
possibly even code snippets to ascertain the cause of the problem you're
having...
