When I click the screen icon to open the menu pgm, which has always worked before, first on Windows 7, now for several months on Windows 10, the FM logo pops up in the tray. Then there seems to be a lot of disk activity, but no menu appears on screen. A right-click on the tray logo shows that my "Mainmenu" program was accessed. No screen flicker that I can detect. Please help! (After years as an application programmer, I'm now a recreational programmer, so please don't be too technical!
