Over two months, I have noticed the game nearly always crashes after a while if I go to the map and repeatedly drag it in some direction in order to see what is some distance from my castle.

For example, if I want to look at all the castles to the west of mine, I would do this:

1. right-click on the left edge of the screen, leave the mouse button depressed

2. drag the map to the right

3. let go of the mouse when the mouse cursor has reached the far right of the screen (but is still in the game window).

I can usually do this at least 20 times, but at some point not too far past that, the game usually crashes and I have to reload the browser.

It doesn't seem to matter which direction I am trying to drag the map.

This causes a problem when I am looking for castles to raid for resources. After the game is reloaded, I can't easily go back to where I left off scrolling, and of course if I scroll back to the same place it will soon crash again.

I use Windows Internet Explorer 11 on Windows 7.
