Hi all, I've had a number of recent installations of the 3CX client, and whilst most of them are working perfectly, every installation on a Microsoft Surface Pro running windows 10 has resulted in the client having poor performance. Trying to place a call results in the app hanging for ~10 seconds with the typical white-out "not responding" being displayed and then recovering. A google search has shown a few other results where people are experiencing odd things when the client is installed on a surface pro. Does anyone have any ideas what could cause this? I've tried several devices, all with the latest patches, removing and reinstalling all the pre-requisite Visual C++ redistributables, disabled AV etc. nothing's worked so far.
