Hi RichM,
Sound like you have done most of the work.
Do you know that you can setup the disable properties when you create your step type. By checking on the Can Specfiy Module, it greys out the menu item in the Sequence Editor. Likewise for Can Edit Code. This would have stopped anyone from changing the code from the sequence editor.
Having a local copy can cause some confusion, but if you had changed the version in the type palettes first. Then when you load your sequence file, you should have been prompted that types had changed and which to use.
Also, even through you delete all instances of a step type in your sequencefile, you also have to delete the local step type version as well, to remove all trace of it.
There is an option in the General Tab, 'Attach to File....', with this unchecked you dont save the step type with the sequencefile. Therefore when all the step are removed from the sequencefile, the type is also removed from the sequencefile as well.
This many have removed some of the problems you are having.
Have you talked to your NI representive directly about the problems you have been having.
