Is there any property to check whether a built in dialog is open/shown?
(Find/Replace/GoTo dialog in particular). Can't seem to find any

I'm working on a VSTO project and i keep on getting a "[xxx] property or
method is not available because the Find and Replace dialog is open".
Properties include, trackRevisions, Paginations, Keybindings etc. And worst
of all, sometimes it throws the error sometimes it doesn't (even if the Find
Replace dialog was always open)

I'd appreciate any light on this behavior
