Forums Bug Reports Fullscreen Bug?

As of more recent versions, I have noticed a slight change in behavior when switching in and out of fullscreen mode (eg, via F11). I can go fullscreen instantly without delay. When I try to return to regular windowed-mode, mIRC stalls while it thinks about this matter.

I usually have hundreds of channels open, as single window maximized MDI view. I have for many many years. I don't recall it having doubts about switching back out of fullscreen before.

Thanks for your bug report. This is because mIRC has to process and update the GUI flags of every window that is currently open in order to toggle fullscreen. If you have that many windows open, this will need to be applied to all of them and will indeed be slow.
