I've tried that fix too...holding down the shift key while double clicking on an item from the item list does nothing to the size of the Edit Item window. I could keep it maximized, but that is not how I work in the QB environment. I have multiple windows open at once and click between them constantly.  I've been using QB since its inception and it seems like I had a similar problem once with a check register doing the same thing, and it seems like the shift option worked for that.  This is the first time I've encountered this problem.
