We (Time Tech) will be looking into this in the next few weeks as we prepare a software package to drive our lab system (we don't want people having this experience). If we can identify the problen I'll post it along with any solution we come up with. Netscape also has this problem. Try using your mouse to select text in a long post (one that goes off the screen). If you move the mouse to the bottom bar while selecting, the screen should scroll. It does, but fitfully. If you move the mouse back & forth on the bar, the scroll speed increases dramatically.
