The brickboard search function requires JavaScript. In Mozilla FireFox, click Tool -> Options -> Content tab and enable the JavaScript checkbox.

In MS Internet Explorer, enabling and configuring scripting, be it JavaScript or Visual Basic (used to work with ActiveX control DLLs), the configuration is more complicated. (I'm using MS IE version 8 on Win XP SP3, so it may be different for you if you are using a newer version of Windows.)

In IE, click Tools -> Internet Options. In the Internet Options dialogue, you can choose settings on the Security and Advanced tabs. These settings you establish on these two tabs can conflict with with one another.

I found each browser has some advantage over another. None is a true über browser. I use Opera 12.x (not the crappy, yet stupid Chromium-based Opera 15.x based on Google Chrome), current FireFox, and MS IE, as updated as can be, on Win XP SP3 32-bit.

MS IE 8, however, does not include a spell check of any sort. Your brickboard posts are not easily spell checked in editor fields in MS IE 8 and owlder. I'll guess MS IR 8 and newer have spell check. Same library and spell check that comes with MS Office, I'll guess. A larger lexicon, using MS Office spell check than the anemic lexicon in FireFox and Opera using U.S. English.

cheers,

Duffed.
