Hi everybody, whoever has a Logitech MX900 BT mouse or knows about BT mice in general, please help me out. I bought the MX900 to have a BT mouse with more than three buttons. I knew they didn't work in OS X except for Expose and that's what I wanted them for. And it works great. But, and this is a huge but, from time to time, the mouse starts to get really, really sluggish, sometimes to a point where it doesn't move at all. The pointer jumps from one point to another and I cannot do anything at this moment. This happens quite often, so it's something that really bothers me, because it renders the mouse almost unusable. I have the feeling that this especially happens when there's a high CPU load though this might be wrong/coincidence. I searched the web to see if I could find someone else with a similar problem but it seems to be only me. So does anyone have an idea what could cause this and, more important, how I can get rid of this problem? Thanks in advance.
