Netscape doesn’t like TechRepublic

Netscape 4.61 on Win2K Pro WS and on WinNT4.0 are having the same problem. After a while – maybe a few days or so between reboots – Netscape will start “freezing” while downloading a page. The status bar usually says either “Reading file: Done” or”Document: Done”, and the icon is animated as though it is downloading, but the page is blank. I can leave it sitting there for many minutes with nothing happening. Interestingly, this usually happens only with the TechRepublic web site – I can browse most other web sites with no problem while it still refuses to download techrepublic.com. Rebooting the system fixes it. Any ideas?
