Steve,

I'm afraid you'll have to post your code. How are you calling the Wizard form? Is it a Dialog? How is the Wizard form referencing the Main form? If you want to reference controls on the Main form from the Wizard form, you'll need to pass a reference to the Main form to the Wizard's constructor. Maybe something like this:

// call the Wizard from Main (assume Wizard is a Dialog)
WizardForm oForm = new WizardForm(this);
oForm.ShowDialog();

// code for Wizard
public class WizardForm : MyBaseForm
{
    private oFormMain;

    public WizardForm(MainForm oMain)
    {
        this.oFormMain = oMain;
    }

    ....

    // in the Load event handler:
    this.oFormMain.next_ToolStripButton.Enable = false;
}

Hope this helps.
