Gene Map tab is not highlighted when selected like the other tabs; it should be consistent with the others.
Usability: Also when the map is small the mouse cursor remains as a hand which makes it very difficult to select genes; user would have to zoom to be able to select.
User is able to launch network view by clicking the button without selecting a gene which leads to an empty pop up window. This should not be allowed the button should be disabled completely.
