Well I can't get the movies to open in the same window either and I've been trying for about 10 minutes...
I can help you with the other though, To test for an active internet connection you can have avariable called 'active' which is default set to false, then you can do a loadVariables request on an online data file: http://www.site.com/onlineCheck.txt
and that will load in a true value for the 'active' variable which you can check later on; if it's true, you're connected, else you're not.
Please don't email or PM

Please don't rely on me reading my PMs either. Email me about important stuff.
