Using 0.9.25I installed version on SP3:

 

When I right-click on a column and select "Hide Column", the wrong column gets hidden. Usually it seems to  be a column immediately to the left or the right of the one I have clicked on.

 

(The correct column gets highlighted when I hover the mouse over it --- it's just that a different column gets hidden.)

 

I should do some more investigation on this, such as experimenting with a sample database and playing with settings, but I thought I'd just mention the issue now in case anyone has experienced anything similar.
