I use KeePass2 to access username/password information in a Dropbox file. This allows convenient access from multiple devices. I can't seem to copy a password to the clipboard on my Linux 188.8.131.52-170.2.117.fc10.x86_64 system, however, in order to supply the password to a prompt in an xterm(1). I've tried both Ctrl+C/Ctrl+V and highlighting and mouse button 2 clicking. The KeePass2 program on the Linux system is executed by Mono.
How can I copy the password to the xterm(1)?
[Aside: I think we need a "KeePass" tag.]
ADDENDUM: My mouse buttons were misconfigured: button 2 wasn't set to "copy". Sorry for the false alarm.
