wine users - Dec 2010 - Programs in WINE are lagging

I'm trying to use various programs in Wine, that successfully run on
Windows. They seem to work in Ubuntu, using WINE. However, there seems to be
lag. Opening Adobe Audition 1.5 is a prime example. It seems to take 3-5 minutes
to "think" about doing so. Executions within Audition are also slow,
such as copy/paste. Same for SAM automation. There is lag in crossfades, that
are not there in Windows operations of the same program. DVD programs  are the
same way too. They also lag when opening.

WINE VERSION is current, per Ubuntu updates. 

Ubuntu version 9.04 AND 8.04 BOTH. 

PC: 2.85 Duo core, 4Gig ram.

Can this be overcome somehow?

Current version means nothing to us.

wine --version to extract a real version number.

Possibly.  Please pick the app with the worst performance problem
and file a bug for it.  Include a description of your hardware
and instructions for reproducing your measurements.
Pick the simplest possible thing to measure for starters.
