Daniel I use 4 monitors. The centre screen is where I open FG. I use browser maximise rather than FG toggle because of the 'focus' issue. When in FG full screen and I click the mouse on FG screen the screen momentarily flashes black. It doesn't do that on browser full screen.
I use my other 3 monitors for various other functions like Mmap, Phi interactive map , Skyvector and general things like email and other online programs of interest.
I also have 2 special panels devised by Surfer Tim and I have ruled them out.
I have no issues when using mouse and keyboard for other functions.
Only firewall is Windows Defender Program
Everything on the computer is mostly FG specific. I use a laptop for other things like general browsing etc. I don't experience a 'focus' issue on the laptop I can have 4 or 5 URLs active and seamlessly switch.
Nearly missed the vital bit. Yes FG does lose focus when inactivity that is when keyboard functions don't work and I have to click on FG then the keys will work. As I say I now have Murgee Auto Click running in the back ground that is keep the FG Focus.
