Re: Printing

I am having a strange problem, I have figured out how to print my widget with the style. However, when I try to print a second widget, I get a blank page. I only have this problem in firefox, I havn't tested in IE, and chrome seems to work every time. Just to be clear I try to print a widget on my site, it works fine, then I navigate to another page and try to print that one and it is blank. It won't work again until I reload the website. Any ideas? Do I need to reset something?

Hi there,

Some people are reporting problems printing with external style links.
I still unable to reproduce the problem in my environment.
Jose claims here http://groups.google.com/group/Google-Web-Toolkit/browse_frm/thread/5bf6997b00dca94a/3acd6b200f77f81f#3acd6b200f77f81f
that he solved the problem introducing a confirm() dialog in the native javascript code.

I think it is a timing problem related to formatting the page using complex html and/or external styles.

Can you try this code below  and report if it works in your case?
