While I was testing Netscape 4.5PR1 on both Linux and Windows 95, I
found an odd behaviour.

If you disable the JavaScript and restart the browser, the "Enable
JavaScript" check-box is disabled. However, JavaScript still works.

The workaround is to enable JavaScript and then disable it again,
every time after starting the browser.

I sent feedback about this bug to Netscape. 4.5PR2 was still broken on
both platforms. It seems that 4.5 works correctly on the Windows
platform but Linux-glibc2 version is still broken.

IMO this is a security problem: if you disable the JavaScript you
usually think that you aren't vulnerable to any JavaScript related
bugs.
