Thank you Jorge for your thoughts,
I suspect that this message is some form of "Error Handler"
of the Plex <--> VBScript run-time "interface", since it is
being displayed in a dialog message (like those of Plex)
which has as title the panel name "360View" of a Plex Client
function of ours. So, it is definitely coming from the Plex
"run-time application" of ours.
My first thought is to request all those messages titles
from the UAT team, locate the functions and add to all
used VBScrips by them the following (when missing) :
On Error Resume Next '...as first line of vbscript
'...Code...
Err.Clear '...as last line of vbscript
And then see what happens.
Kind Regards,
Nicolas Mavroeidis
