Hi,

I'm running Firefox 4 Beta and when I middle click or drag from one monitor to another (while maximised) the titlebar area loses aero and goes transparent. If I unmaximsie it, the titlebar turns black. The strange thing is it only happens when there is Flash on the page you are viewing. To get aero working again, you have to restart Firefox.

I searched the forums, but couldn't find any reports of this. I realise Firefox 4 is in beta, but the issue itself only happens when Displayfusion is enabled. I've tried the stable and beta versions of Displayfusion both with the same result. If I add Firefox under compatibility and disable "Allow middle-click window moving" and "Allow maximised window dragging", the issue doesn't happen, but obviously I can no longer middle click to move it between monitors.

Anyone else have this issue?

Jason

Thanks for the reply Jon. Just thought it may be a DisplayFusion issue due to it only happening when it's running, but it only happening when Firefox is running Flash sounds like an issue with Firefox itself. Hopefully it'll fix itself by the time the final Firefox 4 is released.
