Airdroid doesnt respond or close it self after calling from airdroid

Whenever I made a call through pc using Airdroid , Call become success but after call is finished Airdroid temporarily closed from pc and I have to restart Airdroid from phone.

I noticed this too... I received a call, and after the call I had to go back to Airdroid app on my phone for it to connect again to check new SMS messages on the web
