"Exists" suddenly stopped working with no change in code, where as "VisibleOnscreen" is working.

This was working till last week. Now im getting the error 

Wrong number of arguments or invalid property assignment: 'Sys.Process(...).WinFormsObject(...).Exists'

My guess:

"picMailAddressTip" is a variable to which you're assigning a WinFormsObject...  however, that WinFormsObject does not Exist at the time of execution (possibly a timing delay).

I would replace your "WinFormsObject" to "WaitWinFormsObject" to properly account for the timing delay.
