That's an interesting test case. Did you check to see if Dreamweaver bogs down like that on Windows, too? If it runs fine on Windows, or if you feel like taking a chance: please install wine's debug symbols package (or install wine from source) and then use oprofile to get a system profile while Dreamweaver is bogged down, and send it to us. If it's a Wine bottleneck, that will let us find it. For more info on oprofile, see http://oprofile.sourceforge.net/doc/overview.html http://nouveau.freedesktop.org/wiki/OProfile
