How do I select a new calendar as a "writable calendar"?

Thunderbird 24.3.0/Mac OS X Mavericks/Lightning 2.6.4.

I have a calendar set up to sync with an Internet cloud service (not Google; not iCloud). This calendar has worked fine for me for months and I have many calendar events and tasks on this calendar. All of those can be modified and I can create new calendar entries, but I cannot create new tasks.

On the Task window, in the New Task field, I see an error message that says "Please select a writable calendar". But I can't enter anything in that field. I can create a new local calendar and move existing tasks from the current calendar to the newly-created one, but I cannot find a way to create any NEW tasks on the existing calendar or the newly-selected calendar. Is there someplace I can select this new calendar as the default for tasks? It would be even better to keep tasks on the synced calendar, but I'll settle if need be.

Tasks are not covered by any standards of formatting and almost inevitably do not synchronize. Thunderbird/ Lightning does not synchronize tasks with Live or gmail either.

SoGO claim to have it working with their open source tools.

I already have a preferred conduit/cloud service (i.e., don't want to implement sogu), so I will figure out another way to represent to-dos. Thank you, Matt.
