Ken Primentel posted some news on his offical Autodesk blog about a hot fix for max2012 that should be hitting the street soon
"We're targeting 20 fixes for a Hot Fix release that should be available no later than May 13th. This hot fix represents the most we can pull forwards without increasing our risk of introducing new problems. Hot Fixes don't get the same deep testing as a Service Pack, so there is more risk associated with them."

Be warned the 3dsmax hot fix doesn't fix the "can't save defaults" in the UVW editor, and the editor still lags quite a bit when closing... but some of the other things are helpful, like being able to edit skin weights!
