Mike,

Please don't take me wrong. This reply is only intended to clarify my previous posting...I do not feel like your post is inappropriate, and I hope you see my reply the same way....

I don't believe I was off subject, and I don't think you are either. On the notebook I was using, the way it was configured, either the mouse was active (if the mouse was detected at Boot-time), or the touch pad was active (if the mouse was not detected at Boot-time), but not both.

Either way, we don't yet know what Pamela's environment may be. Even if it's not a notebook or some other combination of pointing devices (keyboard with touch pad or pointing stick, used in conjunction with a mouse), my experience seemed relevant and similar. It may be coincidence that it's only acting up around a grid...at the moment.

Of course it could be something else...I'd like to know what, for the ususal reason. :-)

Rick
