You may be "stuck" with what functions work and don't work. This is the way of free tools. Let's see if we are talking about the same tool?

I do note some copy/paste issue even in Mozilla and other applications. I'm slowly finding workarounds for some. Some are easy like click elsewhere and then back to the place I want to insert the paste, while others in Microsoft Word require that I copy such to notepad, then to Word. Very odd.
Maybe, someday, it will all work, all the time.

Oftentimes, when I minimize the YC screen in order to past a clipping, the last clipping in the index does not show up on the minmimize screen so that I can't paste it. I wonder if anyone knows if there is a remedy for that? I have written to YC about it but have not received any reply. Thanks, Jerry Lyons
