Tower 4 beta locks up

Ground Control Software Tower
1

Just tested the new beta version and it seems to work well. Guided mode with 3.4.4 did just what it was suppose to do.
After powering off the copter Tower locked up and would not respond until I powered the copter back on. Was using a USB 3DR radio set.

Just tried Beta 3 and did not experience the lockup as seen with the previous Beta.
