Headers and fields not in sync

When I have the data-tab open an a specific table and I run a query like this

ALTER TABLE mytable ADD `extrafield` VARCHAR(225) NOT NULL AFTER `id`;

and I switch back to the data-tab, the change is not visible. Then I click refresh, and the extra field is shown.

(So far so good)

But now, I do the same with 1 exception: The sql statement is run outside Heidi. You can click refresh, but the old structure is still shown.

(Workaround: Then I click on the highest level in the left-navigation-pane, click on refresh, choose the table again, and the extra field is shown)

Seems like a small glitch somehow.
