Nope. Just the box model bug that affected all the CSS 2 compliant browsers. ;)

It was indeed a pretty good browser for its time, though.

In 2001 I, for the first time in my life, had access to Macs running Mac OS 9. While I didn't like the operating system much (I was using Linux and Windows at home, the idea of having to assign memory to application manually felt so 80s) I instantly fell in love with IE for Mac. Back then, in PC land, Netscape Navigator and IE 5.5 were the dominant browser, and IE for Mac supported all these fantastic CSS properties that I knew about, but that I could not use in NN4 or IE5.5. I spend hours buliding pure CSS websites without images, simply utilizing unicode fonts, and CSS properties. Ah, those were the days.

Unfortunately it had the most annoying bug in that it did not reload CSS files. Back in the day, I developed with a text editor on mac PowerBook and after changing one CSS statement, I had to close the browser and restart it.

Yea, it was one of the first browsers to implement DOCTYPE switching.

Ehh, IE5:Mac may have been better than IE5:Win, and yes, its CSS and PNG support were ahead of its time, but it was still IE5.

IE5:Mac didn't have support for a lot of things IE6 had that we now consider standard, like :hover for links, for..in, Array.prototype.splice, XmlHttpRequest, contentEditable...
