Txs to Bisente for pointing out how to install Microsoft Internet Explorer 5, 5.5 and 6 in wine on OS X. It's an easy install with his step by step howto. It makes mainly use of tanakas ies4linux, the one-stop-solution for ie on linux and some tools installed by fink.
If interest is there, I might change his script to use darwine, curl, and a precompiled cabextract, so you don't have to install fink to run it. Drop me a line...

PS... here was my post with the little script to install the corefonts to darwine. Might come in handy with iex.
