I seem to recall a previous thread saying that copying doesn't work on Windows 7.
If you mean right click on the mouse and select "copy" or "paste", then Ubuntu 11.10 does not work either. It requires a ctrl-c and ctrl-v on the keyboard.
edit: This malfunction is conditional. If I use the mouse right click and copy, I can use the mouse and paste into a KWrite doc. Then I can use the mouse to copy and paste from the KWrite doc into the forum.
If I try to use the mouse to copy from the IDE directly to the forum, it fails.
