If you subclass a mmMaintenanceForm (ie; mmRolesForm) and modify its datagrid size then the following exception is thrown (it only seems to be thrown when using a TableStyle). This can be avoided by moving the call to this.grdRoles.Size = new System.Drawing.Size(343, 232) from the Initialize method to the form's load method.

CurrentCell cannot be set at this time. Moving your code to FormLoad should solve this problem.
