JQM 1.4.5 Demo View Source
On the demo pages, for example:
If you select the View Source button and then try to select the source it won't high lite the text.
You have to double click in order for the text to be selectable and then when you select the sample text, a lot of non breaking space characters are embedded.
This makes copying source very difficult.
This was not the case prior to 1.4.5.
