Cant move in maps

Hi all,
one of my characters is acting really strange.
He cant move in Maps and levels including monsters. Only in some towns I can freely run around. In my hideout it seems that I can only move to highlighted areas like vendors, NPCS or Map device. But as soon as I go to a map I am stuck again.

Any ideas?
Thanks!

Does this character have anything bound to the left mouse button, such as a skill?
