Hi All
I'm running WSJT-x v2.1.2 0068f9 and JTAlert v2.16.2 and I have the same problem. I'm not inclined to run the release candidates. Attached is my system specs file created with Speccy by Piriform. I looked in Setup> Applications>WSJT-X/JTDX and appears good there.

Hope this info helps. Laurie maybe you can pass this on to WSJT-X dev-list.
Let me know if there is something else I can do.
