Another little, but annoying and not understandable issue on my computer:
If I use the start menu's search box to launch firefox with command line arguments (e.g. -p -no-remote) but without its full path, firefox is launched without arguments...
And on the other side, if I use the run box (Win+R) I don't need the full path and the arguments are used. And if I use another command line (e.g. cmd /K ipconfig) in the start menu's search box there's no problem either...
As far as I remember it's not the normal behavior. And reinstalling doesn't fix it, so how to?
