Ok, WB7 updated and I don't have this issue with the start menu anymore.
The history file state:
WindowBlinds 7.00 beta 2
-------------------------------
New UI
I don't see a new UI, my version still claim to be beta release 1.
If beta 2 has not been released that comment doesn't really belong in the history file, as it's more like a predicition. 
Perhaps 'View History" should be 'Version Information' instead... It would make sense, and info about upcoming features wouldn't be out of place. 
(I'll post the suggestion on the impulse forum too.)
