mfcb - eek, actually didn't do much testing with upgrading to the new index in locked dictionaries - I think for now we'll put up an error message saying that a dictionary has to be unlocked before it can be upgraded. Strange that you managed to start Pleco twice; the first thing Pleco does when it starts up is check whether another instance of it is already running and, if it is, switch to that instance and exit, so this would require rather precise timing...
daniel123 - thanks! Glad you like it.
With undo not working for incorrect answers, if you look at the Card Info after undo'ing, does it seem to have reverted to its old, pre-incorrect-answer score / history / etc? Perhaps there's a bug that causes flashcards to still be reviewed as incorrect at the end even if their incorrect answers were undone.
So you only see Yes and No in that no-cards-due box? Are there any X / cancel buttons at the bottom of the screen? Exactly which WM version / custom ROM name are you running now?
With the no-cards-due error on the frequency test, I'm not able to reproduce that here - how exactly are your session settings configured otherwise? Number of cards, any card filters, "limit unlearned," etc.
"Manage unlearned" is an option in Advanced Settings / Cards; it will limit the number of unlearned cards eligible to come up in each session to a set amount, only adding new ones once existing cards have been promoted to learned. So if you have a list of 5000 new words you want to learn, but you don't want to split them up into subcategories and you can't deal with them all at once, you enable "manage unlearned" and then Pleco will make sure you're not working on too many of them at the same time.
"Stop on partial match" actually ended up with a shorter label on WM, "Partial OK" wedged in next to "Search Dicts" in the "Results" panel in Preferences.
mfcb again - I'm glad things improved on the open programs front. Unfortunately, we really can't pare down the number of files Pleco opens anymore, so I'm wondering whether there's some other issue at fault with HTC Album - have you seen any reports of / had any experience with HTC Album conflicting with other programs? Which ones?
HW60 - oh, "correct in row" actually does only look at the last few answers, or at least it should; if you answered the card correctly three times in a row a long time ago it doesn't count, the last three answers have to have been correct for "correct in row" "3" to let the card through. (if it's not working that way for you, let me know - maybe there's another bug)
Alexis - if you "Unlock" the radical dictionary, does it update then? The card count issue should be fixed in the next beta, it was indeed a glitch in the way we were calculating the total # of cards for repetition-spaced sessions.
