For example, I select "Merged Multi-dict Search" as my dictionary. I do some stuff, no problem. Some time later, after using my phone for other things, I find that the dictionary selected for a new search is some other dictionary. I've never been able to manually reproduce this behavior. I've never been able to catch the moment when the selected dictionary changed, but I've finally decided to ask here about it. All I know is that some time after selecting "Merged Multi-dict Search," in another Pleco session, I notice that the selected dictionary is something else. If this is normal behavior, what sequence of actions causes the change? Or is this the symptom of a bug?
