Is this a common problem? I only use wired trackballs but I notice other major brands of rechargeable wireless mice don't seem to care whether you use them plugged in or not.

What I think would have been better would be to put the charging port on the back instead of the bottom so you can still use it if you absolutely need to while charging but it's just awkward and uncomfortable enough to discourage doing so on a regular basis.
