Cart Link Stock Issues exist in conjunction with UC Stock Notify

Issue Summary

Hello,

Prologue: I have been following this module for a long time. I originally tested it in my old D5.x and we choose not to put it on our production site waiting further development.

I've since installed UC Stock Notify and thought I would revisit this module. I am VERY happy to see how much development has been done and we are now using this on our product site right now! Thank you very, very much for this.

Problem: If you have 2 products, one with stock and one without stock, the page is loaded with the "Notify when back in stock" button instead of the "Add to Cart" button. Then, when the user selects the attribute for the product that is in stock, the "Add to Cart" button appears.

Additionally, this doesn't happen all the time. It seems to be random.

Things I've tried:
** At node/####/edit/options, I tried selecting the in-stock product as the default option, but this makes no difference.

** At node/####/edit/options, I tried dragging the in-stock product above the out-of-stock product, but this makes no difference.

So as it stands right now, some of our products are loading in the browser with the "Notify when back in stock" button despite having available attributes that are in stock, which means the end user would be most likely to believe the product is out of stock and not bother playing with the attributes in order to discover that in fact it is in stock.

Has anyone else experienced this behavior?

Thanks
Mike
