Hello,
Well, I was unable to reproduce the error!!! Hopefully for your changes, but I'm not sure: I changed my code since that error, in a lot of ways, and I tried to restore to the previus version to test, but I'm not sure if it was the same code as before!!!
As I sad, hopefully it's solved. I'll let you know if I see this error again.
THANK YOU!
Vanderlei.


Hi,

I checked some stuff into CVS, can you test it and see if it clears this
up?
