Hover latitude incorrect in southern hemisphere

[eganchris]

The latitude is shown correctly as -38 00 00 for a point with this value.
But a latitude with minutes is shown incorrectly - eg -38 03 is shown as -39 57
The longitude value is shown correctly

This is also occurring for the western hemisphere. As you move the mouse further west or south, the minutes and seconds are decrementing rather than incrementing, and moving the mouse east or north increments them instead of decrementing them.

The degrees is also off by one as the coordinates go from 0°0'0" to -1°59'59".
