Netscape Communicator 4.51, 4.61, 4.7. If using Microsoft IE 3.02 or later, you must have JIT compiling turned off in the Advanced Properties menu. If a later version of Microsoft IE was installed over an earlier version without removal of the earlier version, and you are encountering problems, completely remove Microsoft IE and then reinstall. There should be no proxy server selected. If you are having problems with a version of Netscape you installed before installing CSU, we recommend completely reinstalling Netscape.
