How does BLink work with pop up blockers?

Pop-up blockers may prevent you from composing, replying to e-mails, or opening attachments. You may disable any and all pop-up blockers if this is a problem on your system.

How can I stop my browser from blocking BLink pop-up sites?

To temporarily by-pass pop-up blockers press the CTRL key while clicking the link that is considered to be a pop-up.  In most cases this will cause the browser to allow that particular pop-up to appear.
