Try this instead:
private void CloseOldForms()
{
	FormCollection frmColl = Application.OpenForms;
 
	foreach ( int i = 0; i < frmColl.Count; ++i )
	{
		Form tempFrm = frmColl[i];
		string tempFrmTxt = tempFrm.Tag.ToString();
		if (tempFrmTxt.Equals("NOTMAIN"))
		{
			tempFrm.Close();
		}
	}
}

I'm not absolutely sure of this, but I think that when you call Close on your form, it is attempting to remove the form object from the form collection automatically which is what causes this error since you are at that point in effect trying to alter the contents of the collection over which you are iterating.

Hope that helps.
