Hello,
A big problem is the riched20.dll. We're not gonna have a replacement for it soon, so I think we need to acknowledge that, and accept apps that are not perfect because of it, but are still usable.
It is a serious problem, because without riched20 winzip simply doesn't work, it stops when you doubleclick about a zipped file. Other applicaciones like xnews/icq has the same problem with riched32, without it, the problem is no usable, because, who wants a news/chat program what you can't read the text? ;)
Regards, Carlos.
