Sorry to hear about your trouble with the Table Adapters. I see how this could be really annoying. To be honest we have had similar reports before but we have never been able to reproduce the thing locally so far. Is it possible that you could send over a project where we can see that happening? Be it the real thing or a sample it works either way as long as we can see the thing happening. That's the only way we could have a chance to fix that problem.
As for the IntelliSense we are aware of that problem too and it should be fixed in the service pack we are going to release the week to come. For the time being you could switch off the Visual Aids from the JustCode options. That should get you back the IntelliSense.
