1. Estimating - Entering data in the Estimate detail has now been made simpler. The double click has been removed and you only need to click once into a cell and start typing.
If you enter information in the first column of the first line, you can tab through the columns and just start typing..
Also, if you have added a group of new lines, start typing in line one and tabbing through the first line entering your data. When you have tabbed to the end of the line, another tab will take you to the beginning of the next line as shown below.
2. Purchase Orders - Tax Inc/Ex tick box - this was not holding and has been fixed in this release.
