Just FYI -
I noticed that adobe audition (thru wine 1.5) was using 30% CPU at idle, and wineserver using 22% at idle (when audition was started, but not doing anything). (Shown with conky - values were somewhat higher with gnome-system-monitor)
And foobar's popups (e.g. scroll volume control or song position, a popup shows a numerical value) covered the whole screen rather than being perhaps 20x50 pixels, making it pretty obnoxious to use.
Anywho, I UNinstalled Wine 1.5, installed Wine 1.4 and foobar's popups are the correct size and audition and wineserver use 0% at idle, and appropriately low values when running (about .6% CPU for wineserver).
