When I read a web page, I have to have the mouse in my hand, just like when I read a book, I have to have a pencil in my hand !
Though I have almost grown past my latter habit, it is almost impossible to leave the former one. When I am reading a web page, I have this habit of selecting words as I read. Since a double-click also selects a word, I double click a lot - on crucial words, or otherwise - but a lot.
Believe it or not, even while watching a movie (using VLC usually), I keep fiddling with my mouse. If you know me, you must be aware that it is really hard for me to sit alone and finish a 2 hour movie in 2 hours. I get bored easily and start surfing the net. At other times, I am busy with my mouse doing all sorts of things - including double clicking which toggles the full screen mode.
I have not had any problems with my habit, but of late new generation websites have emerged which consider themselves to be "over-smart", to a level to make the user insane. I am talking about these double-click pop-ups of all kinds which come up when you double click anywhere on the site.
So, while reading, I keep getting unwanted dictionary definitions of the words I happen to double-click inadvertently. Now this is really annoying. The good part is, it will make me get rid of my "mouse fiddling" habit one day. :)
(I hope by the time you are reading this, blogger does not come up with this strategy!!)
You can see one such web page here.
