Map on PC always shows a big white box

[10ccScout 1]

Wherever the mouse is on the map (on the PC) there is a big white box. I has been there for several months, but before, a mouse click removed it. Now it does not go away. This means I cannot see a part of the map about 3cm x 3cm. I have to guess where the cache is that I want to click on as the white box follows the mouse around.

Anyone else have this and can tell me what to do?

I haven't heard or seen this before, but a little more info might help the "guru's" that hang around:  What operating system are you using, and what browser?

Looks like the tile server is dropping one there.

If you move to other locations on the map, where does the box appear, if at all?
