Answer 1

I had this problem with IE and found that the jQuery javascript file was corrupt in the IE developer tool. This was caused in my case by HTTP GZIP compression being done by the server but IE wasn't decompressing the file. I guess that if you turn off static HTTP compression or exclude the application/x-javascript from whatever is doing the compression (Mine was done by FluorineFX for all files over 10Kb) it should work okay once you have cleared your browser cache to get rid of the compressed javascript file.
