Dreamweaver CS3, IE 7 and MCMS

To all,

Have an issue with Dreamweaver CS3, IE 7 and MCMS. Appears that when a user
goes to edit a site, the toolbars disappear. We reloaded IE 7, attempted to
troubleshoot with Microsoft the CMS application and finally re-imaged the
user's machine with an in house company produced standard image. The user's
were able to work with CMS until an install of Dreamweaver CS3 was done. Now
the the issue of the missing toolbars has returned.

Two other user's in the same group installed Dreamweaver MX 2004 and have not
experienced any problems at all. Are there any open issues with Dwvr CS3, IE 7
and MCMS incompatibility?

Thanks for your help.
