I start writing a comment... then I might move to another window to do something... time passes... I do many things in many windows... Then I come back to complete my askubuntu comment... and it has been posted (and I'm not the one who posted it!)

Has anyone else experienced this? ...

eg. When Compiz's "Highlight Mouse Pointer by pressing CtrL" is enabled, it prevents me from using Ctrl+C to copy a file name when in "Nautilus filename-Rename*
... maybe it is something along this line?
