V2.97a.20120527 - Fix for ontimeout() regression. GWT/JSNI compatibility, slow connection and Safari "background tab" SWF load handling improvements
Bug fixes
Fix for ontimeout() regression seen when using lazy-loading / SM2_DEFER introduced with V2.97a.20120513; bug introduced when making edits to pass newer jslint rules regarding return within if...else blocks.
Replaced instanceof Function with "safer" typeof x === 'function' for onready(), ontimeout() and related callback argument checks as GWT + JSNI was passing arguments that failed the instanceof check. (Related bug report.)
Corrected another small regression for the ontimeout() -> onready() "recovery" edge case, ensuring "ready" does not fire after a timeout when init was unsuccessful.
Miscellaneous
Improved handling for special Safari page load case: When a new tab is opened that does not have focus, the Flash SWF does not load/init until the tab is brought to the foreground. SM2 now recognizes this special case and waits until window.onfocus() before attempting to do the JS/Flash part of init. Previously, it would fail with a timeout.
Code written to originally handle Safari 3.1, which did not support document.hasFocus(), was modified and updated for this purpose. The Safari 3.1 logic previously deferred SM2's start-up in a similar fashion. (The old Safari 3.1 mousemove() focus-detection hack has been removed as Safari 4 has been out since mid-2009, and Safari 5 since mid-2010.)
SM2 init process will now delay and retry if no Flash response, and SWF has loaded > 0 and < 100%. Timeout will now happen only after delay and when SWF has loaded 100%. Should help prevent first-visit (non-cached) failure on very slow or laggy connections.
Added note about potential Firefox regression: Offline JS/Flash start-up (viewing HTML pages via file:// and/or c:/ and so forth), possibly not working as of Firefox 9 and newer (at time of writing, also up to and including Firefox 12), even despite special security whitelisting under Flash Player "trusted locations" preferences / control panel.
After successful Flash -> JS call, SM2's "return" JS -> Flash call fails with unusual JS/Flash exception, "Error in ActionScript" error with no further detail. Offline viewing still works in other browsers.
