tax value rounding error on 4 places after decimal point

Hello Quick Books smart person,
I have Quick Books 5.0. I am using Windows XP. I just now had to change my sales tax percent from 7.75% to 8.25%. It never calculated the tax so badly before. This is what it did to me. For a $35.00 charge to my customer QB calculated $2.90 tax. My hand held calculator calculates it $2.8875. This should round up to $2.89. What gives?

Thank you for your help.
