Map scrolling

I have expanded it out to the max view, however, I find it horribly slow, makes it very difficult to place towers.  Because you can't move around the map quickly.  Maybe there's a setting haven't played around with it much yet.  

Edit: You can change this in options..  Change Bind Cursor, (I changed it to never, then you can move the focus of the screen with right mouse button.)  You can also change Camera Pan Speed  (I changed it to 300%).  This helped greatly.  Hope that helps.

I've noticed this too.  I'd describe it more as the map having too much inertia than just moving slowly.  If I'm scrolling with the arrow keys then it will take a few seconds for the map to start moving at a reasonable speed and it will continue drifting for several seconds after I release the key.

It isn't tied to a specific zoom level.  If I change the zoom and then return to the original zoom level I can scroll around just fine.  Also, using right-click to move the map around will fix the issue.

Having the map continue to scroll after I have moved the mouse away from the edge of the screen is one of the most annoying things I've seen in a game. Not that feel strongly about that or anything...
