Blogger Problems

I'm trying to work on a Christmas post about stuff that I did over the weekend, and Blogger is being difficult.  When I got to the point in the post where I wanted to add photos, I clicked on the photo uploader icon on the tool bar, it was quick to tell me that I can now drag and drop photos directly into posts.  Okay, sounds like a new feature.  I clicked the 'Got It' button, to indicate that I understood, and now, when I click the icon to upload photos, all I get is a blank box.  It should contain the upload features and previews of my photos ... GRRRRRRR!!

Seems to me that Blogger updated something and broke it in the process.  

Anyone else having this problem?

Edited to add:  I shut down  my computer, started it back up, and now the uploader seems to be working.  Wish me luck.
