Intermittent: Gadgets Very Slow to Draw

The first time I connect to a Vista 32 machine I have to wait :30 to :60
seconds while the Vista side bar draws gadgets, then redraws, then redraws
again. I can't select or do anything while this is happening.

If I disconnect and connect again, the sidebar and gadgets are drawn
immediately and all is well.

Can anything be done to avoid this? Is there some kind of cache-ing going on?

Thanks.
