vim in xterm with "set mouse=a" and system clipboard

[alex.blackbit]

hi,

i use vim since ages and just discovered the "set mouse=a" feature. very handy.
but there is one drawback. text that is selected with the mouse in the vim window does not end up in the system clipboard.
that means i cannot paste it in e.g. a second xterm by pressing the middle mouse button.
can i tell vim somehow to copy selected text in the system clipboard ?
i read about that "* register stuff, but it does not work for me.
anybody with more success ?

Coping with the middle mouse button across xterms works fine here. What does not work is from a xterm to a gnome-terminal but the other way around just fine.

Looks random to me.

thanks for your answer, but i am not sure if you got me right.
copy/paste works correctly in all kinds of terms, including from vim windows.
it only does _not_ work if i do "set mouse=a" in vim.
