A few months ago I posted a similar question and got a reply from
Thomas Morgan. He sent me a file in from Squeak 2.1 that fixed the
problem for me (I was running 2.2). I have not tried it with 2.3
though.

I've placed the file at:

http://www.cnd.co.nz/squeak/HTTP.12Nov921pm.cs

Thomas Morgan supplied it to me, so thank him for it, not me :-)

Hope this helps,
