A problem with i.class...

Dear Grassers,

I am trying to do a supervised classification for land uses in my study area. I had a data error
problem when I capture a region to analyze the signature class in this region. When I start using the
Analyze region Menu I get this error message;

WARNING:PREPARE_SIGNATURE: DATA ERROR (CLICK MOUSE TO CONTINUE)

Has anyone got this kind of error before. I worked out about five signatures before I got this
message, I think it is BUGS in the program. Any clues........

Many thanks,
