I use it yesterday on my PC at the brothel and it worked great.
 
Today and tomorrow I am at home with my Mac and when I click on the TER Messenger, NOTHING happens.  It doesn't pop out.   Can someone advise me

I can't get on CHAT either.  Sounds like a Flash problem maybe???????  Please help!

If you're using Firefox on your Mac, go into Preferences and under Content look at the first line that says "Block pop-up windows". If you have that checked, you can un-check it. Or you can add TER to the exceptions by using the Exceptions button.

If you're using Safari, click on the Safari link at the top left of your screen. In the pull-down menu you'll see an option for blocking pop-up windows. If that's checked, select it to un-check it.

Yep that worked for me!  I am on Safari and new to Apple!  Thank you!!!
