Hello,
Unfortunately, I cannot reproduce this on any of our machines. A "Display Wait Dialog" should always close a previously opened wait dialog.
The following works fine here:
Display Wait Dialog
Display Message Box "We are here 1" -- ""
Sleep for "2" seconds
Display Message Box "We are here 2" -- ""
Display Wait Dialog
Display Message Box "We are here 3" -- ""
Would it be possible for you to send us a small demo script?
Thanks,
