I cannot Turn off Type Assist in my Current Workspace

When I start a new drawing, I do not want Type Assist to make changes to the text I am entering - especially its "Capitalize first letter of sentences" rule.

I've tried adding a new Workspace based on the default with Text Assist turned off, saving it, but to no avail.  When I open CorelDraw and start a new diagram, the darned Text Assist is back on again.

Can anybody suggest a way I can eliminate Text Assist from any new drawing when I start working on a new one.  In my line of work, what I enter through the keyboard should be recorded in CD exactly as I type it - no changes.

Incidentally, I am using CorelDraw v9.439.

Any recommendations would be greatly appreciated.
