The mouse generates interrupt signal (Ctrl+c) at Terminal
 

ubuntu 8.10 was installed on vmware. I opened:
Applications-->Accessories-->Terminal. when I drag or double-click my mouse on the terminal, The interrupt signal will be generated. I don't know why?

What symptoms are you seeing?
What are you doing when the ctrl C occurs?

If double-click or select text on the terminal, interrupt will happen.
