I have encountered some problem with content getting partially written over other content. Clicking on the reload button always fixes the display. I have noted this while working with my article edit029.html, which is a very long page. Rerely notice any problems elswhere.
It has finally fixed the problem with the "back" function (buttons or keystrokes) often not working on IWeThey (never noticed it anywhere else). This has brought up another minor problem. When using the "back" function on IWeThey, the previous screen may not be drawn, leaving a blank white page. Don't know if this is unique to the OS/2 version or not. In any case, the reload button (or keystrokes) draws the page, and it's a lot less anoying than the back button problem was.
Very occasionally a page will be rendered in the wrong font. Once again, "reload" fixes the display.
