Exchange 2010 and Powershell v3 Issue

I decided to take the plunge pray and install powershell v3. I like it so far but I am having a few problems. One problem occurs when running the search-mailbox cmdlet. It starts to run and as soon as it seems like it's finished my powershell windows closes arbitrarily. Event ID 4999 show in the application log. Same with ISE.

Watson report about to be sent for process id: 3480, with parameters: E12, c-buddy-RTL-AMD64, 14.02.0247.005, PowerShell_ISE, unknown, M.E.D.S.N.PropertyDefinitionSets.BuildWellKnownSets, System.TypeInitializationException, b3a, unknown.

Another problem im having is warning messages that show when running some cmdlets before they actually run. They are always the same so far.

below is the warning...
