Now you see it, now you don't.  I've just discovered that if I turn off my firewall suddenly my WYSWYG buttons appear.  Now I'm going to try the evasive spell check.  Hold your breath.  HURRAY IT WORKS!  THE PROBLEM HAS BEEN SOLVED.  THOSE FIREWALLS CAN BE PRETTY TRICKY THINGS.  Sometimes they block the very things you want and at other times don't block the load of garbage that they are suppose to filter.
But it's a great day for I finally figured out the spell check problem.  I now see that Blogger has added a number of features to the toolbar line.  I'll have to investigate.
