Well, I'm not the moderator in question, so I don't even know what the original title WAS. Be that as it may, let's see if we can sort your actual issue out.
Correct me if I'm wrong; it sounds like you've got a 'launcher dock' at the top of the screen.....and your taskbar is opening on top of it? Should be a simple fix.....and there's absolutely no need to 'automate' moving the taskbar down the screen. You don't have to; all you need to do is to make sure you have the correct display setting for the 'launcher dock'.
Assuming the newer versions of JWMdesk still work largely the same as the older ones, open JWMdesk -> tab 'Tray'. Look for the 'Autohide' setting (under 'Geometry'), and make sure it's set to 'Standard'. What this does is to hide the 'launcher dock' until you actually need it for something; to show it, simply move your cursor up to the middle top of the screen. Bingo! it appears again......but do be aware, you can't move your cursor away from the dock itself, THEN go back to it.....because it's disappeared again in the meantime. Once the dock is showing, you do need to keep the cursor inside it until you've clicked on what you wanted.
This way, your taskbar can show as normal, yet you can always bring the dock as & when required. It's tidier, AND more practical.
Or is this not what you meant?
(The other alternative is of course to move the taskbar back to the bottom of the screen. I believe most people have things this way, because it's a PITA trying to have the dock AND the taskbar both occupying the same part of the screen. Or, you could set it so the dock sits down the side edge of the screen instead..... It's up to you; what do you want to do?)
