My main.prg sets the path to LIBRARY subdirectory (which contains the main.vcx library) before calling my classes.
Most of the time the main.prg runs fine and I can instantiate my classes from the main.vcx properly. But sometimes I get an error :

main.vcx can not be found.

I am using 5.0a version.
Maybe this is a bug on 5.0a version?
Any clue on this problem.?

Thanks,
Sergio
