Power BI Desktop Refresh Slow

I just upgraded to the latest Power BI Desktop Version: 2.32.4307.522 64-bit (February 2016).

Since the upgrade, when i attempt to Refresh the data from SQL Server, the application loads the rows from the table(s) and then just hangs for about 5-10 minutes. (Even for a small data set like 1000 rows.) After some time the application will then complete the refresh.

Anyone know whats going on here?
