Rikaikun pops up where it mustn't

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Enter your Facebook account
2. First, use Rikaikun to look reading of some Japanese text
3. Close Rikaikun's pop up window by clicking some white space on the page
4. Click on a comment box to give it focus
5. Leave the mouse cursor on some white space area
6. Start writing comment under something
7. Rikaikun's pop up windows pops up and shows reading of some irrelevant text 
that you didn't look for before

What is the expected output? What do you see instead?
I should had been write my text without any interruption.

What version of the product are you using? On what operating system?
0.8.1

Please provide any additional information below.
While writing text in textareas, Rikaikun pops up and the textarea loses focus. 
And this happens even if the mouse cursor is on a blank area. It happens almost 
half of the time. The bad thing is that it pops up after I start writing, if it 
had popped up before I would had move the mouse in another place.

I feel like this has happened a bunch of times to me too... or if not that, 
I've at least had tons of trouble with using text boxes on pages featuring lots 
of Japanese. After clicking in a text box to activate it, it seems sometimes 
while moving the mouse away, it will detect that it's hovered over some 
Japanese (which de-activates the textbox), even though I could've sworn I 
carefully navigated the mouse in between any Japanese text (lol).
Also, I seem to recall running into problems if I click in the text box and 
then leave the mouse be and start typing (in Japanese), but trying to reproduce 
that problem right now in this text box is not working... That is to say, 
Rikaikun IS working properly in this regard here in this textbox.

But yes... Whatever the cause, I seem to get interrupted by Rikaikun pop-ups 
some way or another quite a lot of the time when typing in text boxes.

I was just reading some other posts/issues, and it's come to my attention that 
you can get around this by disabling "highlight text" in Rikaikun's options.

That is to say, it prevents active text-boxes from becoming de-activated.

Rikaikun will still show pop-ups when it shouldn't, but it seems this prevents 
the interruption in typing. I'm so happy to have just discovered this. I hope 
you are too. =)
