Long startup lag. Often accidentally trigger hotkeys (which cannot be reassigned) when typing. Biggest problem I have though is it now no longer works inside Google documents. I do some translating (J->E) and used to get a lot of use from rikaikun when editing a Japanese document in Google docs. I don't know if this issue was caused by Chrome, Google docs, or some change in rikaikun, but this is enough for me to take off another star.

The app itself is very good, but sometimes it just stops showing the english translations, I have to reinstall it everytime to make it work again.

Its really the best app I found until now for Kanjis. Most other get the reading wrong. My only annoyance is that the popup window is too striking, it should have an option let it be a bit more transparent.
