Well it looks like I can use jquery to help this situation out, but of course the results vary browser to browser.
By setting the height of all 3 of my streams with JQuery I’m able to get the footer to slide up and display.
$("#twitter-widget-0").contents().find(".stream").height(‘367’);
$("#twitter-widget-1").contents().find(".stream").height(‘367’);
$("#twitter-widget-2").contents().find(".stream").height(‘367’);
note: My widget height is set to 442 and using firebug I was able to see that the one timeline properly showing was setting it’s stream height to 367.
This worked great in Firefox, but seems to be causing mixed results in IE. It’s still rendering too low in IE and I’m noticing other styles that were not properly applied on those hidden divs as well. Hm… back to playing around with some settings I suppose.
