Hi Mike,
Thanks for your reply, you guys trying to reproduce the problem is much appreciated. Though in a way it's kinda unfortunate that you don't experience the same issue, of course...
Going through your list of things, here some more food for thought, and at the end there is maybe a hint towards the cause of the trouble, indeed, thanks to a point you've made.
General:
Sure, the fact that you can't reproduce it and there are no more than 3 (!) reports here and now indicates that it's an isolated problem, most likely depending on a specific environment or browser setting or plugin. But us 3 here could as well be only the tip of an iceberg... the few who are getting back to you here...
1) - 3):
I've been running my own install as well as your demo site on another Mac with "virgin" Firefox 26 and Safari 6.1.1.
Same effects: In both browsers the animations on the Helion homepage have first stalled. Then FF gave me the warning as per my recent attachment, and since clicking on "stop" I only see the OS X beach ball spinning. Safari didn't bother giving me any warning, but has as well stopped responding. Even force-quitting the browsers was a major act since the OS had gone into extreme slow motion...
Not sure if relevant, but please note that the crashes happened latest after clicking around on the homepage a bit - e.g. clicks on the accordion thingies, mouse over main menu, etc. Actually, I'm not even sure if the problems would occur if the homepage was loaded and then left alone without any activity.
However, while I'm on a local Mac/MAMP install, users Rokk and Marialee are on different web hosts and various OS's and browsers. I do not have any Windows PC here to see how it'd deal with the problem in this part of the world. But anyway, we have no control over what gear and browsers/plugins visitors of our websites will be using, and asking them to re-install their browser clean is not practical at all. So, other than for the purpose of finding the cause of the trouble, I fear your advice 1) - 3) is not helpful, especially since, again, even my clean browsers crashed, too.
On to 4), which was good because searching the Joomla forums produced something, maybe. I'm not the expert, so please forgive my amateurish attempt to explain:
You stating,
we haven't added any new scripts or extensions to the Template and it shares the same Framework as all our previous Vertex Themes
plus the fact that many people with custom JS scripts had trouble with J3.2.x seems to be pointing towards the cause, IMHO. Helion Site Launcher comes with J3.2.x, but if you haven't altered your JS scripts (or the order in which your loading them, respectively), then problems can happen, seemingly. The key seems to be in the "noconflict" script loading/handling, and with you having one as part of the template as well as Joomla having one natively, it seems to be easy for things to get messy.
Please see the following threads:
I have not tried e.g. the deletion of a "noconflict" script file yet. In the interest of others here, and probably yours as well, I thought I'll check with you first. Again, please keep in mind that I'm no expert, and have also not bothered comparing your code in previous and actual templates:
Perhaps you could verify and confirm that your scripts have been adjusted to those specific JS requirements of J3.2.x as per mention in the Joomla forums since you claim compatibility with J3.2.x? If such adjustments have not been made, it is likely no wonder if your code doesn't work well with J3.2.x...
Admittedly, it wouldn't explain why you can't reproduce the problem... unless you (a) used Joomla 3.1.6 or older, and/or (b) only loaded the homepage but didn't click anywhere (see hint above).
Anyway, thanks for continuing digging into it. I do like the Helion template very much and intend to build an e-commerce site with it... if it works, that is...
