TABLESPACE bug in Toad 10.1

In Toad 10.1

In Schema Browser TABLESPACE dropdown

When you switch to another database (or instance) the RHS DATAFILES gives the
correct results for the new instance. But the OBJECTS tab still shows the same
objects as in the original. It looks like it does not update the grid.

Is this fixed in 10.5

This is not fixed in 10.5. This is the first I have heard of it. It will be
fixed in the next beta.
