Video/plugins window problem. L9.1 or Mavericks related ?

[Valiumdupeuple]

Hi.
I'm facing a problem I never had before.
I use an 2nd monitor to display Live's video window (the problem also happens with 3rd party plugins window).
What's pissing me off is that each time I go to one "space" or "desktop" (Mission Control) and come back to Live's space, the video (or plugins) window doesn't stay on the 2nd monitor, but comes back on top of Live's window.

I'm facing this seriously annoying behavior since L9.1 b23 (around that), BUT, this also coincide with the day I've upgraded my SL to Mavericks.
SL didn't have Mission Control and I never used Lion or ML.
So, to those who are/were on Lion or ML, does this problem already occurs ? Or is it a problem introduced during L9.1 beta, or Mavericks ?

(I've reported the problem to Ableton team, but no answer yet)
Cheers
J.

Just in case someone faces the same problem, I've found a solution :
Open Live's 2nd window (L9.1 feature) on your external display, the video window will now stay on top of it.
