Edited Unassigned: Stand alone resx program slow to scroll [4741]

I have 25 languages and only a few hundred keys at most. Vertically scrolling the content takes a second or two per page. Dragging the scroll thumb is out of the question since the window updates this slowly. I am using the resx resource manager as a stand-alone program since it sometimes crashes or hangs in VS or causes VS to crash or hang.

Also, sorting on a column takes more than a few seconds. These problems seem related.
