Well, the only workaround to the UpdateWrapper errors was to 'after, 500 $mw-> a widget that fails to pack. Do I know what that does? Not really. Seems like a timing hack.

Good news, that.

#$mw->deiconify; Works, but something steals focus from the app

$mw->after(500,sub{$mw->deiconify}) Works, focus stays with the app

The first code doesn't "dwim", or seem to work as intended. Why the second method does is the question.

I always iconify/withdraw my $mw on startup so everything draws, then deiconify. It looks nicer when opening the application. I haven't done any PTK coding for a few years, back before XP was my OS of [not my] choice.

Anyway, there is not a question that there are issues. Finding why and having a global fix or recommended practice is the goal. 

I'd move to using Tcl, for example, but I wish to bundle this app with pp.

This is the main error: "UpdateWrapper: Failed to create container"

Thanks, any suggestion or clue is a help.
