This is my first post here... and a got a question.

I'm not sure if this is the right place to post but anyway:
I'm writing a letter with koma-script using evlab and mlabel commands.
When compiling and the mlabel.lco is not in the same dictionary as the .lyx file, I get the errormessage, that the "mlabel.lco" file is not found.
If I put the .lco in the same dictionary as the .lyx everything works find.
So, here's the question (finaly): Where should I put the mlabel.lco so it will be always found, no matter where the .lyx is?
hope you can help me!
