Scott:

We are seeing something very strange as well--on some computers that update, our application does not work. It won't even let us reinstall. Checking the rights to the directory and everything seems correct. 

After a reboot, and a reinstallation of our application, everything works fine. 

We use FB 1.5 embedded in most applications, but are running the server version on several computers and it is running just fine.
