[gme-users] change in integer limits in Constraint Manager?

Hi Steve,

You're right, now that the constraint itself doesn't cause
problems, there is no value I can give to this type of 
constant that will cause a constraint violation in GME.
Zoli, is there any way I can deal with this in GME?

thanks,

Jeff
