I have a couple of processes in which the database schema changed. One of them isn't correctly updating SQL and I was attempting to run a debug session. I changed the default database schema to the new one however I can't continue as I get the error message "Cannot Focus a disabled or invisible window". I have searched the logs but am unable to find this error or what is causing it to get past it.

Thank you in advance for your assistance.

Close your Workfkow Configuration tool (or if it doesn't want to, kill it).
Then double-click on your Workflow Configuration tool icon, to open it, while holding down the CTRL keyboard key until the software in completely started.

That will reset the default settings to factory default.

That didn't seem to help; unless I've completed the steps incorrectly.

From Tools :
Server Status -> Stop Service
Server Status -> Start Service (while holding CTRL key)

I did also attempt to close Workflow completely and restart services to no avail. This is occurring on my my dev and prod servers.
