GUI Question

[Gunderak]

Hey,
I'm into JavaScript quite a bit and am wondering is there any way to prevent the default actions? In JavaScript if you wanted to prevent something, like when you click on something you'd do preventdefault();
Iv'e tried some things, but with no luck.
I know you could simply make it resize back to normal when resized, but it looks shabby.
This is regarding an external window, since canresize has no effect on it.
Cheers.

Tried posting the things I tried but incapsula..... ugh.
