What George said. Here is how I've handled it before using the keyboard. Note this is hard to describe to a customer and if you're not keyboard oriented yourself it could get weird.
From the Windows taskbar click on Sage (and you can't see it still obviously) do the following:
* Hold down the Alt key + spacebar. This is same as clicking on the top left stub menu where you see Restore, Move, Size, Minimize, Maximize, and Close options.
* Press M on the keyboard for Move
* Hold down your keyboard arrow key (either left or right) to move the Launcher into the main screen. It's just like dragging with your mouse. I like trying the left arrow key first since most secondary screens are on the right. If it doesn't become visible soon, then hold down right arrow key.
Worst case is if they are using the Classic Launcher, then renaming a specific registry key under HKCU and restarting Sage will force the Launcher to reload in its default screen, position, and size. I think it's this one:
HKEY_CURRENT_USER\Software\Sage Software\MAS 90 Business Desktop
I think @BethBowers remembers this better:
