Hi there!
I might have discovered a tiny bug in the UI of Publisher:
Create a document of any size with any number or pages.
Put a text frame on any page and set the number of columns to 2.
Use the context tool bar to increase the gap between the columns. It stops at 33,9mm no matter what.
Open the text frame panel and increase the gap beyond 33,9mm - easy job.
Return to the context tool bar (which has been updated to the number you entered in the text frame panel) and try to adjust the gap again. It always switchs back to 33,9mm
The bug affects both the retail version (.703) and the current beta (.874).
