I already tried with shortcut properties, checking rus as adminstrator on and off.
Does not help.
Even the exe file had the b/y shield in the c:proram files(x86)\Fritzing
So i copied the fritzing.exe to fritzing2.exe so i have 2 versions.
The sketches are on a linux server (samba) mounted to H:\
Did right-click refer to the fritzing2.exe program.
So now i have 2 fritzing in the context menu.
Just like the Beatles, I ... Let it be, let it be
I think i let it be.
