No worries.
It decided to start working again.
I think it was something to do with the Selected User not being the Current User, because this was all I changed to get it working.

I've got a weird one in PL/SQL Dev 9.
When I do an explain plan (F5) on a query, there are no results in the plan table.
This works fine in PL/SQL Dev 8.
Same query, same database.
Any ideas?
