After several hack installs (10 or so :D) I noticed that the login/register function no longer works with Netscape. It just hangs on a blank screen.

All the other board functions seem to work fine. These are the board calls I seem to be having trouble with.

I tried using stock template files as a quick debug, but the problem didn't go away. Which modules are involved with these routines? If someone can point me in the right direction, I can probably pull off a fix. Or if you're familiar with this Netscape glitch or have any suggestions, your help would be greatly appreciated!
