I am running the latest KiCad (4.0.2) on Windows 10. However, the KiCad Window does not show. If I press Alt-TAB to toggle between programs, the window is shown in the preview but not as an actual, usable window. I already had the same issue with 4.0.1 and updating to 4.0.2 helped for a short time - one program start to be precise. I am now stuck with using eeschema and then changing to pcbnew etc. from there.
Is this a known issue?
