Left Click...no click...sometimes

[HUGGY]

Hey TWIMC.... Within the last week my left click in "reply" has been acting strangely. It is functioning perfectly now in this post but when I try to reply to someone elses thread ...and even in my own threads the cursor doesn't show up blinking when I attempt to say something in the bottom of the reply box. What I have done previously is place the cursor right next to the last entry of the message in the reply box and hit enter to start my post. Now it locks up most of the time but only in a reply box.

Any thoughts or help?
