Inserting the check in the MAIL checkbox in the "Make Thunderbird the default application for:" box does NOT work because the box "unchecks" itself as soon as the OPTIONS menu is closed. This is a minor problem, but hasn't been addressed in many months. Reproducible: Always Steps to Reproduce: 1. Open Thunderbird 2. Check the "Do not display..." message that appears 3. Answer "Y" to "set as default" question 4. Open TOOLS/OPTIONS menu and select Thuderbird as the default application for MAIL 5. Close OPTIONS block. 6. Re-open OPTIONS block and note MAIL selection is unchecked. Re-check the box 7. Close Thunderbird 8. Open Thunderbird and note that the "Set as default" question reappears Actual Results: The same. The "Set as default" box appears every time Thunderbird starts. Expected Results: Set Thundrebird as the default mail application and NOT displayed the message. None.
Still see this in 2.0? Please upgrade and report back. If it doesn't seem to work, reinstall into another empty folder - that usually helps when registry entries are messed up.
2.0 did it. I've been trusting the built in update system and it apparently didn't know there WAS a 2.0! It kept downloading 188.8.131.52. Thanks for the help!
