Copy between open source members in RDP 9.0.0.1

I am having issues with copy between open source members in RDP 9.x. I
posted before, but I am hoping someone has found or knows of a setting to
make this work since then.

Symptoms:

2 open members - can be CL or RPG.
Use Alt-L, then Shift-Up or Shift-Down arrows to highlight a section of
code, from 1 to n lines.
Use Alt-Left or Alt-Right arrow to jump between source members.
Use Alt-C to copy the highlighted lines between the members.

This USED to work in previous version all the way from 6.x to 8.5. It still
works in my 8.5 install, but I hate to go back to that just for a quick
copy between CL members. In 9.x when I look at the source members side by
side, the highlight stays until I press Alt-C, when the highlighting
changes shape or goes away altogether, and nothing gets copied into the
target source member.

It will work correctly if I take the slow cumbersome way of grabbing the
mouse to select the source I want to copy into by clicking on the tab for
the target source member. Then I can use Alt-C key shortcut to copy the
highlighted source.

Alt-Left and Alt-Right arrow still jumps between source members, but
something messes with the highlighting so that when the copy shortcut is
used RDP does not remember it had anything to copy.

This is driving me nuts, and for me lately it is a very SHORT drive, in
fact it might be a putt! ;^)

Any thoughts? Fixes?

Thanks
