Locate and repair overlapping button

When preferential screens are created and later modified, it is possible to accidentally have buttons that overlap each other. 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.

Locating Overlapping buttons

Overlapping buttons can happen when enabling the Right Expand or Bottom Expand options next to existing buttons. Buttons to the right and below the expanded button still exists, but are now hidden by the expanded button. This will cause unexpected behaviour with the Advanced POS User Interface.

Fixing overlapping buttons

To fix the issue, you can disable the expand options and leave them disabled. You may also delete the hidden buttons before re-enabling the desired expand options.

Unfortunately, there is no easy way to spot overlapping buttons. The only way is to open the properties of each expanded button, disable the expand options and see if there were one or more buttons hiding behind it.

Overlapping buttons in Screen Layouts

Overlapping buttons can also be found in Screen Layouts. The procedure to locate and fix them is exactly the same as for Preferential Screens.
