Thank you for the idea and fast reply, already looking for a way how to hookup on events (newbie in this language)

(A bit slow after lunch: it will not work, if I dont have that version...)

Is there a way to know, if the path finding took too long or just failed?

No, please dont do it... Dont start this thing. Making the game more simple, easier for the dumbs. It was a reason I stopped to play WoW.
There are steps you have to follow, there are rules you have to keep in head and you will get a bigger feeling of success / achievemt later. Not cheap wins right ...
