The mouse on my remote computer and host computer are all of a sudden not aligned. I can see both the local and remote mouse at the same time and depending on the screen resolution I set it at, they are anywhere from an inch to 8 inches apart. This makes it very difficult, if not impossible to control the session.
The host monitor is 21" and the remote monitor is 27". I also tried it on my laptop which is 15.5", and it was having the same trouble. A couple hours later it seemed to resolve itsef.
