To avoid crossposting, I'm going to point to a recent post on Vista issues here:

See what you think.  I can't tell yet if these items are one-size-fits all, but for me they seem to have fixed a couple of the Vista issues.

If they strike you as useful, add 'em.  If off-topic, I'll pull this post.

Thx,
