Whenever I try to create a dialog in IE7 I get a javascript error message.

I investigated the problem and located it to the function called "size()".

In ui.dialog.js, this is the function called "size()":

The function is trying to retrieve a numeric value of the margins.

(variables called "tbMargin" and "lrMargin").

In my IE this results in a NaN.

I solved the issue by adding the following lines below:

if(isNaN(tbMargin)){tbMargin=0;}

if(isNaN(lrMargin)){lrMargin=0;}
