Ok well somebody already posted these exact directions but I'll try to make it more simple.
Open Land Desktop 08 and 09, or 07 and 09 for that matter it shouldnt really matter as long as its no later than 07.
Right click next to your drop down menus at the top and select "Customize". (you need to do this in both versions of Land Desktop you have out)
Click the arrows at the top of the "Customize" window pointing down labeled "Customizations in All CUI Files"
and the arrow pointing right at the very bottom of the window next to the "HELP" button. (you need to do this in both versions of Land Desktop you have out)
In the "Command List" section at the bottom left of the "Customize" window you now have open and expanded, it should already be on ALL COMMANDS. Change the commands your viewing to Tools and scroll down until you see the Command "Bring to Front". There will be more than one so make sure you select the one whose source is ACAD.
After you've selected the command on the right part of the screen labeled PROPERTIES there will be a row labeled MACRO, to the right of Macro is the code for that command. (you need to do this in both versions of Land Desktop you have out)
Now in the Land Desktop 07 or 08 version select the whole code and copy it. Go into the 09 version and select all of the code and paste the older code over the 09 code. This will erase the 09 code. If your worried about losing your 09 code and my directions ruining your Land Desktop than just save the 09 code in a text document and fix it later if this doesn't work. However it will.
Do the same thing to the "Send to Back" command and then apply and test it out.
Hope this helps those of you who have not had much experience in the CUI interface.
