Me again. Maybe answering my own question. For whatever reason, the ABC and NWP options disappeared on their own after a few minutes. Did they uninstall themselves?
If so, I now have a totally different question. (maybe I should start a new thread but I hate to mess up the forum) For whatever reason, it never occurred to me to try the Tutorial in the Manual while I was still in Demo mode. I basically just played around and asked question in this forum. Now that I have done the tutorial with only Oxford installed I am discovering that the examples in the Manual must be from ABC and NWP. And that what I find most appealing about my favorite dictionaries, i.e. the providing of examples of sentence usage in pinyan, as shown for example with "aiqing" or "anjing" doesn't seem to happen with the Oxford dictionary. Am I wrong about this. Should I have purchased the ABC/NWP package instead of the Oxford? I guess if I had understood PlecoDict better I would have realized all those examples in the Manual were not with the Basic package. Still, I wish it had said so.
