I finally figured it out...The attached signature file was 'blocking' the write command. Dumped it and all is working. thanks for your help..

Safeboots - I hope its windows safe boot, not thunderbird.

To diagnose problems with Thunderbird, try the following:

  • Restart Thunderbird with add-ons disabled (Thunderbird Safe Mode). On the Help menu, click on "Restart with Add-ons Disabled". If Thunderbird works like normal, there is an Add-on or Theme interfering with normal operations. You will need to re-enable add-ons one at a time until you locate the offender.

Create a new profile as a test to check if your current profile is causing the problems.

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem
