Works in Main Application mode but not the orange NXT mode for some NXT's

[SuffolkProf]

A simple Labview program designed using only NXT VI's worked  in the Main Application but not in NXT mode.  For some NXT's it  worked in both modes but for others, just in Main Application mode. I've tried  updating the firmware and plugging and unplugging the USB.  Any thoughts?

It is strange that you are seeing different behavior on different NXTS. Could you post your vi and also explain what the expected behavior is versus the incorrect behavior you are seeing on some NXTs.

I am just using the NXT VI: motor.  The VI runs fine in Main Application mode. When I switch to the orange NXT mode, Labview can not find the NXT.  Another NXT works just fine in both modes.  So the problem is with the NXT and not Labview. Is there anything I can do about it?

I see. The problem is probably that when you are switching to the NXT Target mode, it is expecting to target the other brick to which you already deployed. If you right-click on the orange banner menu in the lower left corner, you should be able to select the other NXT, or use "Find NXT..." to scan/search for bricks.

Also, I reccommend giving all your NXTs unique names so this is more obvious. (you can use the NXT Terminal tool to do that).

If you still can't get the VI to run in target mode, restart labview.
