If I:

(1) have source bar enabled

(2) am entering items into the Item column in a grid

(3) switch away from Infoqube to another program and then switch back to Infoqube

the cursor always jumps to the Source Box in the Source Bar.  So that if I try to type something, the effect is to change the source for the grid.  I can always "cancel" out of changing the Source but is a pain.  It would be better if the cursor were still in the grid when I switch back to Infoqbue from another program.
