one more detail the add:
Once this window popup, TestComplete paused there and showing me "Waiting for window: WndClass - "#32770", WndCaption - "xxxxx"", at this time I even couldn't click Stop button to make it stopped, the only thing to make TC recover is to close the window.
Looks like the window is the perfect enemy of TestComplete.
No. Thats a bog standard Windows Dialog window.
I have a Delphi application. Some errors and popouts use Delphi generated windows. Some of them use the standard Windows Dialog. Depends how your devs have built it. You just need to handle them.

If the caption varies, and you have mapped it using the caption as an identification property (sounds like you have), then the window won't be found next time it appears.
Thank you Colin for your reply. I didn't use caption to map it, I use xxx is just to replace the real caption but didn't mean it is varies. :)
TestComplete can't handle it no matter with mapped name or full name. We have this #32770 dialog window in other module with C# and can handle it well, except this one. :(
