Hi, I think I maybe have a related problem (see SSL annoyance). Do you ever get some hangup behaviour? I mean, when you try to modify a big page or to upload a relatively big file does your browser hang (the progress bar still moves but nothing seems to happen)? I've tried with different version of Zope (2.6.x until 2.7.0b4) and M2crypto (0.12, with Windows python 2.1 __m2crypto lib recompiled because it was not working on my PCs) both under Windows and Linux Now I can tell that with Zope 2.7.0b4 this behaviour is still present with only Internet Explorer while, using Mozilla/Netscape everything works just fine. I know this doesn't solve the problem but it could be useful to me to know whether it is a common problem or not. Thanks, Mario
