When preferential screens are created and later modified, it is possible to accidentally have buttons that expand beyond the screen boundaries. This wasn't much of an issue with the Legacy POS User Interface, but this can lead to random crashes or even the POS not starting at all with the Advanced POS UI.
Logon to the MaitreāD Back-Office with appropriate credentials. (Distributor or System Owner)
Start the Point of Sale Control module.
Click on the Screens menu and select Preferential Screen setup...
The list of available Preferential Screens is displayed.
Select an existing preferential screen and click the Modify button to edit its properties.
The Preferential Screen Editor will appear (Legacy UI mode).
On some occasions, it is possible to have buttons where the Right Expand or Bottom Expand options are enabled but grayed out because the button is on the edge of the screen.
This happens when copying or moving an already āexpandedā button to the right or bottom edges of the screen. It can also happen if the screen's properties were changed. Here are a few tricks that can help in identifying problematic buttons:
If the screen has fewer than 50 buttons, increase the screen size to quickly spot expanded buttons and fix them before reverting to the original screen size.
Here is an example with āScreen 18ā where everything looks normal:
Increasing the number of buttons by switching to āScreen 36ā shows that some expanded buttons were actually hiding on the edge of the screen:
50 is the maximum number of buttons that can fit on one screen. To quickly spot problematic buttons in this case:
Make a mental note of the buttons that are on the rightmost column and on the bottom row.
Click on the Screen button and change the screen to a smaller button count, for instance āScreen 36ā.
Use the Previous and Next buttons to navigate across multiple pages of buttons. Look for any button that looks awkward. The text and graphics on problematic buttons will appear truncated or strangely formatted.
Fix the buttons by disabling the appropriate expanded options.
Revert the screen to its original size. Click the Close button to save changes.
The same issue can occur on Screen Layouts. However, there are no fancy tricks to detect out-of-bounds buttons.
Logon to the MaitreāD Back-Office with appropriate credentials. (Distributor or System Owner)
Start the Point of Sale Control module.
Click on the Screens menu and select Screens layout setup...
The list of available screen layouts is displayed.
Select an existing screen layout and click the Modify button to edit its properties.
The Screen Layout Editor screen will appear.
Unfortunately, there are no fancy tricks to detect problematic buttons on Screen Layouts. You need to double-click on each button that is located near an edge and look for grayed-out expand options:
Next, you will need to move the button (drag & drop) to an empty space that will allow it to expand properly. Then, you will be able to disable the Expand options and move the button back to where it was.
