minimap borders

One annoying thing that I've noticed with the minimap is that is appears to be overlaid by the two 'find' and 'turn' buttons by a small amount. So, for example, if I want to click on the lower left of the minimap to move to a star in the area, I find myself clicking the 'turn' button by accident. Moving the mouse slowly around that area shows that the turn button lights up when the mouse pointer is well into the minimap window, and not just a pixel or two.
Am I the only one to find this an issue? I was quite surprised not to be able to find any similar posts on the subject.
