Hi. I am not sure if this is a HW, Win7 (64 bit) or Kicad problem, however I have only observed the problem in Kicad.
I have a laptop that I sometimes connect to an external monitor. I often disconnect from the external monitor without shutting down the computer. Usually this works fine, but then I "lost" the PCB calculator. The program seems to start and is available in the task bar, but the actual program is "invisible". At first I believed it was on my external disconnected monitor, but after reconnecting the monitor, the program was still "invisible". Even after rebooting the PC the program was "invisible". As long as it was only the PCB calculator that was lost it wasn't that important, but now the same thing has happened with the Library editor, and thats a lot worse. Anyone that have an idea of how to fix this? I have not tried to reinstall Kicad yet.
