Hi there,
I hoped it is just a very odd issue, that FSX-SE won't start in full screen mode after EZCA 2 launches, but I had to realize it is true. Ather that I found a line in FSX.cfg under the [MAIN] tab, calls "Maximized=" and I set it's value to 2. EZCA or FSX always writes this value back to "1". My FSX starts in an ugly small window every time. I have no luck, and yes full screen is feezing when I hit shift+D (show EZCA window).
Other problem, I found the HAT switch movement laggy (slow) and I decided to turn it off back to basic FSX settings and I failed, totally impossible.
