Slip Listing Window Text is Invisible

SOLVED

We're using Timeslips 2014 in Windows 10.  We have several computers attached to a server that hosts our database.  On one of the client computers, the text in the Slip Listing window is always invisible - no matter what the filters.  This happens every single time.  There are selectable colored rows representing each of the slips. but the text that should show up in those rows is not there.  I tried uninstalling and reinstalling.  The rest of the computers, running Windows 10 and connected to the same database, do not have this error.  What's the problem, and I how do I fix it?  Thanks for any help anybody can provide.
