enable proofing can be slow (64bit 6.0.9)

Hi

When I use the "enable proofing" button it seems to switch all windows, including those that are completely hidden.
I thought that pwp was crashed when I had a lot of windows open (+50) and hit the "enable proofing" button, but it's easily tested with making a few copies from the same image and then switching between proofing and non proofing.

Switching from "enable proofing" to "disable proofing" is fast.

BTW. Apart from the slow switch I would love to have the possibility to "enable proofing" only on the active window, because this is usefull to do adjustments when proofing. (having a "disable proofing" version side by side with a "enable proofing"version.)
