Hans,
on Windows 0.39.3 you could [ctr] [click] to change values while in edit mode.
That made working and checking quite fast.
Now it only opens a context menue which is already there if you [rightclick].
Please put it back to the old behaviour. This would also make sense on Linux in my opinion.
On Mac I don't know with the one button mouse still being in use?
