Mark,
As pointed out, you stand a chance of not getting everything right if you
just pick a decoder and start doing writes. The values you see when it first
opens are the 'default' values which may not reflect the values in your
decoder. Common practice I strongly suggest is that for each pane in the
decoder pages you would do a 'read sheet' first, then make your changes,
then do 'write changes on sheet' to update the decoder. When done you should
go back to the first decoder pane and do the 'save to roster' to create the
file of your changes. Then this is available with better data for any
further changes. From your description, the 'read first' may not have
happened before the 'write'.
