[Plugin: Sharebar] Major alignment issue in IE8

I just noticed that this plugin works fine in Chrome and FF. However, I just checked it out in IE and see a major problem. The bar is right in the middle of the page. Scrolls fine, but it starts in the middle as if it didn’t get the left side positioning.

I figured it was a problem with my blog, but when i visited the plugin creator’s homepage (https://devgrow.com/sharebar-wordpress-plugin/), I have the same problem. This is a little different. On this page, the plugin starts in the right spot and then when I scroll down the page, when the bar hits the top of the page it jumps to the center of the page from the left.

So, it’s not just me.

Any ideas?

Thanks,
JMR
