Tabs for saved searches display black

Hello everyone, I have set up six saved searches, each tab with a custom colour. If I click on any of the tabs, the colours display correctly, but not if I click on the binder. Then the other tabs display black until I drag the cursor over them. Is this a known problem?
(BTW, I love love love Scrivener!)

Yes, this is a logged bug that occurs if the Binder tab has been dragged above other tabs–clicking on the Binder tab will then black out the ones below it rather than using the proper colour.
