Actually I just noticed a but that sometimes happens when using this. 
Routing in Mapsource can get broken if not in resolution 24. So once you 
zoom out, and point with the mouse somewhere, the tooltip shows up 
somewhere else!
If this is pretty close, you will instead be routed to somewhere else, 
or clicking into the map makes no routing at all.

I can remember that the "wrong" tooltip location happend around one year 
ago with mkgmap too. It was then solved later on (don't ask my when, was 
it the introduction of routing?), maybe with 1410 we have run into that 
error again.

- I'm currently trying out if any particular option is responsible for 
this, or if this new revision is the cause for the failure (upon closer 
inspection I noticed the same problem for "patch v8" - simply overlooked 
it before).
