Yes. Until 1.0.7, crm would build all completion tabs at startup.
Then, as of 1.0.7 it also loads the help directly from the
manual. It turned out that the startup time would be quite high,
so I made both the help and completion tabs lazy built, i.e. they
are done only when the user enters a level (and cached). That's
exactly what you saw. Anyway, you can open an enhancement
bugzilla and I'll see if we can get all completion tabs built if
we're in an interactive session. And how would that affect
performance.

Thanks,

Dejan
