In Claris Resolve 1.0v2 & v3, there is a issue in the N-Solve function when formatting a cell or row of numbers.
* Go to the Calculate menu and choose Matrix- N Solve
* Go to the Format menu and select Set Format to display specified number of decimals for the row (other than default)
* When you reactivate the calc or add new entries , the formatting reverts back to the default 2 decimals.
Formatting numbers using the N-Solve function reverts back to default setting.
