[PD] canvas window "relocate" message strangeness ...

[oliver]

Hi,

i just discovered a really strange phenomenon when opening patch windows 
with remote messages

Attached is a test patch that presents the "problem":

The window is always opening with active scroll sidebars, even though 
there's nothing to scroll.

The only exception is, when the "relocate" message mechanism is done "by 
hand". Messages that are sent remotely or with a delay produce the 
scrollbars.

It really seems that the visual representation of a clicked BANG or a 
[message box( comes into play here, though i don't understand how or why.

It seems as if only as long as the window messages are passed WITHIN the 
"visual representation time" (in lack of a better description ... i mean 
the short thickening of the border of a message box when it is clicked 
with the mouse) the window is opening as it should (without sidebars).

I discovered this phenomenon using the [propertybang] external from 
IEMGUTS, where the window would only open with said sidebars.

To make matters worse, this behaviour is not consistent, but seems a 
little random. What's sure though, is that only a direct mouseclick onto 
a bang or message box reliably opens the window without sidebars.

Feels a little voodoo-ish to me ...

Cheers

Oliver
