For whatever reason, and only in Financial --> Account Maintenance, the VCR buttons in the bottom left corner of the screen are not visible. Users were using a modified screen for this task, so I checked on it in modifier and the buttons are there and set to visible.
Thinking it was something wrong with that particular modified screen, I set all users back to the default account maintenance screen, but the buttons were still missing.
Taking it one step further, the same problem exists after migrating the data to our 'test' GP 2013 system that we will be migrating to live shortly.
Is there a security setting that prevents users from navigating through accounts using the VCR buttons? I'm out of ideas...
