Will be updated if we can get fixed builds out sooner than currently scheduled.Stephan commented
In over 15 years of Access development I haven't seen a screw up to this degree. I have clients that have limited or significantly slowed business operations for the past week because of this, I don't understand why Microsoft hasn't put this at the top of their priority list and fixed it yesterday, because I know I'm going to get more calls today.
