If any of you folks use (or have used) the FlashCan software I announced here a long while back, you may like to know I've blown the cobwebs off it (having re-booted my attempt at learning the language) and given it a handful of updates and bug fixes. Mainly fixing glitches but it now supports tone insensitive searching, and searching within the romanised form using the numeric Yale format. The supplied Cantonese dictionary has grown too, now with 740 entries in it.
While I'm not learning it, the website also now has a donated Mandarin dictionary file using the simplified characters.
As always, bug reports are welcome ^_^
