I can use the drag function in other programs and on internet sites (minimized this page and dragged corners, etc.). No problems with the mouse. It's wireless and working fine.
I can still drag borders in AW's other windows. For example, I can drag the border between Shipping Options and Item Specifics on the Inventory Items window; I can drag to change the width of columns on the Email window; and I can drag column widths back and forth in grid view. Looks like the problem is exclusive to the Auction Lots window. Soooooo frustrating!
I feel like I should add a Do-Not-Try-This-At-Home warning. If you drag the Images window over to within a quarter-inch of the left, I think you're probably ok, but if you drag it all the way over, uh oh!
