High CPU usage when disconnected

Post by tony359 »

Hi there,

I am using 1.2.1.5 and I found that when the connection is severed (because the remoted device is disconnected or switched off or I simply put to sleep my laptop and open it again some time later) the UVNC service is using quite a lot of CPU power.
I've found my laptop with a flat battery when left unattended because the remoted device had disconnected and the service had used up all the available battery.

Just wanted to report this. I'll see if downgrading helps. If more details are needed, please let me know.

Thanks
Tony
