Hi HeideMeister,
There is nothing that is jumping out at me as incorrect in the Label
subclass code you posted above. However, do you know if the mouse over style
gets removed in the case where the Label is added to, say a regular
VerticalPanel or to the RootPanel, or does this issue only occur when adding
the TabHeaderWidget to a TabPanel?
Cheers,
