i.e. the context menu for setting 'Parallel' for a subproject doesn't quite finish the job.

Works for me. The tasks of a parallel subproject within a sequential project are not available unless the subproject is the first incomplete item within the sequential project. For example:

- Sequential Project
    - Action 1
    - Parallel Subproject 1
        - Action 2
        - Action 3
    - Parallel Subproject 2
        - Action 4
        - Action 5
    - Sequential Subproject 3
        - Action 6
        - Action 7

Initially only Action 1 is available. Complete Action 1 and Actions 2 and 3 become available. Complete both of those, plus Parallel Subproject 1, and Actions 4 and 5 become available. Complete both of those, plus Parallel Subproject 2, and Action 6 becomes available.
