Sergio,

I very quickly ran the app wizard.

In the appwiz class library there is a container class called wzapplication. It has a custom method called DoForm. TLNOSHOW is a parameter name for this method. I searched throughout the project and this is the only place I could find it. Since it's a parameter and since it's refered to in the code as a logical, it *should* always be defined. It will be .F. if the parameter isn't passed.

So, long story short, I suspect that you have a problem calling this method somewhere. It's just a suspicion. I'd step through my code line by line to find which line exactly is crashing the app and then work backwards.

HTH.
