2010 CanTax income tax software from CCH - the worst tax software ever!!!

I have been doing personal income tax preparation ever since taking H&R Block's income tax course in the fall of 1988 and worked for H&R Block during the tax season in 1989. Back then I prepared taxes by hand using the tax forms, provided by Revenue Canada, and a pencil. The pencil was necessary as it is easy to erase a mistake when it is written lead.
