When I start a new listing, I put in the Title only and then save. Once you successfully save your listing once, it seems to go smoother. I usually split my listing into three parts: the basics, the pictures and the description. I save after each part. Then if it freezes, you don't have so much to redo.
By saving at intervals, I seldom have a listing freeze on me anymore. If it does, I close that window and open a fresh one and then redo the last step. It seems like I either have to do it this way or be constantly deleting my cookies and such.
