>>When I move the mouse pointer over the horizontal sizer bar above the message in the lower right portion of the screen, my vertical height sizer mouse cursor never comes on so I can adjust the height of the frames. I could in IE4 but now I cannot adjust the Frame Height.

>I just checked; neither can I, or at least the mouse cursor never changes to let me know I'm in the right position. In fact, the cursor doesn't seem to consistently recognize the frame boundary (or at least there are times where the cursor type doesn't change immediately.)

The frameborder attribute for that frame is 0. It's not the version of IE, Michel has changed the HTML.
