Entering in large journal transactions with many lines is very difficult because the scroll bar does not work. This applies to Jiwa 7.00.175 and earlier.
The issue impacts Jiwa versions 7.00.175 and prior. The problem has been logged for correction under DEV-5684 for inclusion in the next public release after 7.00.175. In the interim, use the *Splitter *function of the grid. In the top right corner of the grid, hover over the splitter (exactly the same as Excel or Word), drag and drop it half way down the screen. Use the second pane to scroll and enter data in the last lines of the journal.
