My first thought was that you were in manual calculation mode, but you indicate it is only random employees, not every employee.  You do not indicate if it is the same employees all the time though.  If so, then I would suspect you are using recurring transactions and they were originally saved in Manual calculation mode.

We are not using manual calculations and we are not using recurring transactions. All individually done up at payroll time. And yes, random employees, not the same all the time.

Any other ideas?

Most of my ideas are blown out of water by your comment

but when we RECALCULATE taxes, the correct $$ appear. Have checked everything, # of pay periods, payroll tax settings in employee records, all employees making enough to be calculating taxes

I don't understand why you have to go into Adjust mode to recalculate the taxes.  You should be able to do that before you post.  Is the Recalculate button available when you start a paycheque?  If so, then you are in Manual mode when you open the module.  Check the buttons on the toolbar.

I can see CPP not calculating even if you have the checkbox checked if you have entered the wrong year for the employee's birthdate.  That happens more than you'd think, but it doesn't account for EI and Tax.

Are you still in History Mode starting up your company file?

Absolutely not.
