When I click on the "Insert Image" icon in TinyMCE, it opens the image dialog, but when I click on the browse button to browse for images, the window opens but it is completely blank.
The browse button has this JS:
javascript:openBrowser('srcbrowser','src', 'image','theme_advanced_image_image_browser_callback');
I see this in the Error log (though it's from the the NewsPublisher attempt):

MODX 2.2.1
TinyMCE 4.3.2
I've tried completely removing and downloading and installing a new TinyMCE, and clearing the cache and the browser cache and cookies, but the problem remains.
It's a localhost install on Windows Vista, so it's not a permission issue. Curiously, when I try the same thing from inside NewsPublisher, it works (though the image preview is a broken image).
Any idea what could cause this?
