Netscape problems with PHP

Hello all (first post for me!): I've been running into problems when testing PHP scripts on Netscape (when MSIE works fine). First problem (SOLVED) was that Netscape does something funny with the $PHP_SELF environmental variable, so I've learned to circumvent the problem by just hard-coding the page name instead of relying on the $PHP_SELF trick. Second problem (UNSOLVED, SO FAR) is that Netscape (...and I'm talking about Communicator 4.75 for the Mac, at least) doesn't carry my session variables over from page to page. Has anyone else ran into this problem and found a solution? Thanks!!! P.S. Things seem to work fine in the new Netscape 6, but most Mac users are still at 4.75. -- Robert Fischler, PhD ABD IUB Campus Manager CampCampus.com
