    Hi All,

    I am running Thunderbird in Windows 7 on my MacBookPro and Windows XP in a Parallels/boot camp install on my MacPro.

    I am also running Thunderbird (actually also Mail and Postbox at the moment) on my laptop as I desperately try and get my emails and contacts sorted. TB on the PC has a certain create contacts in bulk from emails functionality that I need at the moment.

    On the laptop in Win7 I get the following error when I try and start TB:

    "Thunderbird is already running but is not responding. To open a new window, you must first close the existing Thunderbird process, or restart your system".

    Any ideas? Postbox, Thunderbird and Mail are all closed when this happens.
