Spurious Initiation when a Widget is open

[pikurasa]

When a widget is open, Music Blocks seems to be hearing spurious cursor clicks.

To reproduce, open a widget, leave it open, move cursor around the screen. Even without clicking anywhere, pitches will be played and the open widget will reinitiate itself.

Especially bothersome when Status Widget is open. Also observed with Phrase Maker.

I was able to reproduce something similar to this ,
steps:

1. initialize more than one widget : status and phrase maker .
2. close phrase maker , modify pitches inside phrase maker.
3. phrase maker initializes again and starts playing abruptly.

I am going to close this for now.

Just FYI, when I was testing the slider, I clicked some of the Hertz blocks, and a few seconds later--without clicking on anything--the same pitches played in the same order a second time. I tried to reproduce it a second time, and the same thing happened.

I am going to keep a lookout for this behaviour. @sksum please do the same.
