Blank Webviewer

[KaosMaker]

I'm having a problem with the webviewer, in that I cannot see anything on it at all. This just started happening, and I have no idea why! Even if I go in and hardcode the URL, to something like www.filemaker.com or a local file path, nothing happens! Not even a file not found, so I'm disinclined to think it's a connection problem.

And no, I am not in find mode by accident.

If I try to grab the source, all I get is

. This is happening in all files, but only on my computer. Other computers on the network can open the same files without a problem. It used to work just fine, but I don't know exactly when it stopped working. Could I have broken it with a new java update, or something?

Thanks!
