The program is great, but theres a bug in the latest version. When you try to link any set of cards to the Dropbox, for an unknown reason the program goes to the background mode and (if you have stickystudy for kanji) kanji stickystudy opens and links THIS program to the Dropbox, but not the other one.
As a result of this bug, I had to delete one of stickystudies to link one of them to the Dropbox. Please fix it, guys. You find this bug in both stickystudies.
The new design is great by the way!
