I'm sure you'll find a way
If nothing can be done... hum make it so it becomes teh height of the player window and the width of the hotbars... It will go in place of the player and target window.... resize the player window so it's now teh width of teh old group window so it can be placed in it's place.. actually make it as you wish since I have no problem with teh width and height of the journal help.
Sad.. very sad this group window...
