Font Navigator is missing "Contents of Font Catalog" and "installed Fonts"

Normally font navigator has 4 sections inside the window and mine now only has 2.  What happened was that the window was shrunk and the top 2 sections kept getting smaller and smaller, until they went missing.  I can still adjust the columns from left to right, but no longer from top to bottom to get the other 2 sections back.  I have moved my cursor all around the area and it never changes to let let me make the horizontal bigger.   How can I get them back without having to uninstall/reinstall Corel?  They still have to be there, I just can't figure out how to reset the window back to normal.
