In the purchase invoices journal, for some companies, I can tab into and type the amount of the gst and pst directly in the tax column.  But for other sage files, that option is not available and I have to click on the little icon to the right of the tax amount in the bottom right of the invoice and then click in the pop up screen to change the tax amount.  Added steps which takes additional time. I have set up most of my client files myself so it must be something that I am doing differently during set up but I have compared many files and can't find the source of the difference.  Has anyone else encountered this?  Any suggestions would be greatly appreciated!
