Just a had problem where typing a number triggered VAX suggestion list containing a bunch of unnamed structures. After cleaning cache and rebuilding symbols the problem went away. I have no idea what triggered the problem in first place but there seems to be a bug somewhere in VAX:) Using build 1527.
ups, should have searched before posting. Well as my support ended I can't install anything later than 1527. Guess I'll have to switch back to 1301 once again.
