Strange wireless Intellimouse problem

I experienced some strange problem regarding to my wireless Microsoft mouse. There were a few situation which the system seemed to have problem letting the left button of my mouse to commit on commands like clicking OK or dragging some item. However, the same left button on my mouse had no problem performing other functions such as dragging windows.

And the strangest thing is on the "solution" of the problem. I fixed the mouse left button problem by plugging in my wired Logitech USB mouse, use the wired mouse to left mouse click some stuff, and then use the wireless mouse again. After then, the problem went away.

So, yeah strange indeed.
