I have the same problem with VW 10.5.1 in OSX 10.3.5.
I had made some nice scripts that rotated selected objects interactively around a clickpoint by steps, left or right, according to pushing the '-' or '+' key.
Another script moved a person on a particular stair, to see interactively the free headspace.
There was also a script that showed in the message palette the ascii-code of every pressed key with or without modifier keys.
Unfortunately these scripts are not usable anymore for me.
I would be very happy with a solution for this problem.
