One specific example. I have database form (I don't know if that make a difference to the behaviour). If you bind it to a sqlserver bit field it automatically interprets is as boolean as it should. The default values are true/false (pretty logical) and with an additional select option.
Usually I want the display value to be Yes/No rather than true/false and I just want a blank option rather than the select word that appears. If I copy and paste, even before I have changed the binding, if you look at the properties it is back to the default true/false/select options. It seems to happen every time without fail.
Thanks for letting me know not being able to copy rules isn't available, that would definitely be a nice thing to have in the next version.
