Execute() starts a modal mode, so it is not only understandable but also 
required that further *linear* execution of the script stops (handlers 
registered to buttons still we be called).

If you want to have more than one dialog, you have to execute them in a 
modeless way. I don't know if

oSticky.SetVisible(True)

works (I even don't know if UnoDialogs export an XWindow interface), but 
that's how it is done with C++ dialogs.

Besides that you will need to redesign your dialog a bit, modeless 
dialogs usually don't have "OK" or "Cancel" buttons, because they 
directly act on the document when their buttons are operated by the user.

If your dialog logic makes it necessary to have an "OK" button, most 
probably a modal dialog is recommended and no other dialogs (except sub 
dialogs) should be operable while it is visible.
