I'm using Java Preferences API to store window position and size of Swing application. At this moment, I'm listening to window resize/reposition events and storing the position and size every time they change. However, that means that if user slowly resizes window which is 200px wide to 400px wide, I'll probably write new window size abo...

I'm trying to keep a boolean preference in sync with a value in a content provider, and succeeding nicely except for this issue.

As far...
