When I copy/past from the filter to another table/filter then I have problem with this.
Keyboard shorts CTRL+C and CTRL+V sometimes work, sometimes not. This same is with a mouse. Right click open the menu and sometimes Copy is working, sometimes not.
Also when I try copy to terminal. First time I copy from a right click menu Copy field, then I go to terminal and SHIFT+INSERT and gave me value of the fields, second time give me something which I copy somewhere else before.
Please let me know if you also see this problem or this is only my local problem.
My system: Debian Sarge.
