I've tested it also with WinRAR, WinSCP3 3.30, 7-Zip and Pirch98 (the 
last two have Bugzilla entries and are fixed by the new code). The only 
thing I've found not to work are the sidebars of IE. For the next week I 
won't work on wine but what should I do later - would such a big patch 
be accepted?
