Comment 8 for bug 621459

In web client 3.0 using the 'mark for' menu, marking a record for overlay can be undone by then selecting 'reset mark' in that menu. If you 'mark local result as overlay target' this does not show in the 'mark for' menu. You can tell what record you are overlaying because both tile side-by-side but if you decide not to do the overlay this record will stay 'marked' and there doesn't seem to be a way to unmark it.
I could duplicate Elaine's experience. I refreshed the Z39.50 tab and it was still marked; I opened a new function in the tab and went back to Z39.50 and it was still marked. I logged out and back in and it was still marked.
