ToME: the Tales of Maj'Eyal

Sry for my bad english in some places, english isn't my native languange.
When i played tome4, i randomly pressed something, and my character started to move a much slower then he was, tried to set speed on 0, but it didn't helped. Then i have decided to delete settings folder, then i discovered that this trouble is still in game, and now i cant attack npc just by simple click, i must right click and select attack in menu. How to fix it? Big thanks.

In regards to no longer being able to bump attack: Look in the top left corner, under your character portrait. If you see a shield there click it and it should change to two swords. That will re-enable your ability to click on enemies to attack them.
