editing rows in pgadminIII

Hi,

I've noticed that in my pgadmin for linux the focus jumps from the 
column I'm entering data into after initiating editing with F2.  For 
example, I click on a field to edit, enter data, then tab over to the 
next field.  I then press F2 to start entering data.  After typing the 
first character, then foucs leaps away, and I need to click on the 
still-opened field in order to resume editing.  This isn't a huge deal, 
but the need to take one's hands off the keybord wastes time.

This doesn't happen on pgadmin3 for windows.

Sound Familiar?
