Two issues just now after patch. First, lost the mouse curser in flight so can't check settings, preferrences E6B, etc. Second, in the middle of a fight at low altitude - ground to 5k, suddenly went to desk top. In a 51, using flaps to turn, but not keyboard, hotas only. Clicked on game icon on the menu bar and got right back in, right in front of the F4U that shot me down. Ooops. Great game. Frame rates stay solid at 59-60 (my max) low, at altitude, in fights, flak, etc. Love it. Only a few settings cut back -- playing well above the default settings.
