I have a bluetooth mouse which usually works ok. Basically, I did a one-month assignment elsewhere and didn't have a problem. Once I came back at my office, I observed the same behavior again. Basically, once I have used the mouse after a period of time, it starts acting as if the connection is not good. So, the mouse skip on screen and this causes some unexpected behaviors. It seems to happen when the surface has been used for a while as if the temperate is changing and that start affecting the mouse. If I move the mouse over that surface, it is ok. I tried putting a different surface but it is the same. However, as I said, I only have this at my office. Could it be that when being used at the same location after a period of time that some interferences could happen?
