New user here as well. Similar problems. Sometimes it goes unresponsive. Sometimes a disconnect/reconnect fixes it, sometimes not. Sometimes there are just certain windows which do not allow me to do anything, i.e. Admin Command Prompt, Task Manager, Device Manager. I am on W10 v1803 and experienced these issues on both a W10 v1903 and a W7 computer. All three systems had CB RA installed yesterday, so all the same version and all the current version. I also experienced continual minor scrolling on a web page in Chrome while logged into the W7 system. The page would not stay steady for me to see/read.
