Some months ago I changed from the release to the beta channel. At some point during the 91 betas I started getting a message box saying 'There is no email program associated to perform the requested action. Please install an email program or, if one is already installed, create an association in the Default Programs control panel.' twice every startup. On starting Thunderbird I first get a message box saying that, I click on OK, the box closes, the box opens again with the same message, I click OK again, the box closes again and then the Thunderbird window finally opens. Every startup. Whether I'm starting TB or it is re-starting after an update. In Windows 10 Default Apps settings, Email is set to Thunderbird, .eml, .wdseml, MAILTO and MID are set to Thunderbird. In Thunderbird settings I've set and re-set Thunderbird to be the default for everything but Calendar, also done it again after running TB as an administrator. I've used a reg file I found that's supposed to deal with problems in the Registry that can cause this, and also downloaded and run the current 92 beta installer after finding the problem still there after TB updated to the 92 beta.
Everything appears to work after it starts, but having this error box and having to OK it twice every re-start is getting really annoying.
