I do, quite well. Proprietary features are miles away from cutting edge web-standards. Being locked into only one browser that works correctly is very, very much different from being able to chose from among many modern browsers (in the typical case).
More so, as I said that particular problem was not nearly as bad as people targeting the rendering of their site to the particular quirks of one particular browser. That was horrible, but it's not even remotely the same problem we face today.
