I just updated to CMSClient 1.00.00.50 on Windows 10 64 bit and now the arrow functions to move the camera do not work, the sound no longer works, and if I try to move one camera with the mouse from one window to another (ie. click and drag camera 1 to camera 2 box), the CMSClient crashes and closes down. The cameras do load much quicker with this version. When I login the cameras display straight away, on previous version I have to click "Start Monitoring" 9 or 10 times before it will display, but losing all of the features mentioned above means I have gone back to previous version of the CMSClient v1.00.00.49.
