What steps will reproduce the problem?
on "Selection of the viewers" tab I
1. Uncheck all viewers because I dont need them.
2. continue to Render phase and
3. REnder.

What is the expected output? What do you see instead?
It is expected only tile files exists but all meta files and viewers
generated. sometimes it took very long time to generate these meta files. I
only need tiles not metadata.


What version of the product are you using? On what operating system?
On Windows XP Pro using MapTiler 1.0 alpha3

Please provide any additional information below.
I want to tile more zoom levels then calculated so I write minimum and
maximum zoom levels by hand.
