Love this plugin but document component plugin doesn't work with Opera

I really love this plugin and I’ve had it since its beta version and I just finally got around to using it last night (getting around to writing a review of it for my blog. 🙂 Though I was using it in Google Chrome and the components I was using working fine. However, when I went to check the posts I did with Opera browser, the document component ‘reader’ window showed only a gray area and a message saying “This plugin is not supported”. I haven’t yet checked the other browsers I use, Firefox and Safari, to see if I would get the same error but will. But so far, Chrome handles the document reader component fine. I thought that the incompatibility may be due to a problem with either Java script or Flash so I updated my Flash player for Opera but still I would get the same error.
The other post I did last night was using the content component and that post looks fine in Opera.
