Sorter and TextExpander incompatibility?

Just auto upgraded to the latest DTPro, and got the following warning in TextExpander:

Looking through the preferences I don’t see a way to turn this off. Quitting Sorter and / or DTP doesn’t seem to help help.

Any ideas?

And a restart later, the problem seems to have gone away. I can now seem to open and close DTP and Sorter without this recurring.

Move along now. Apparently nothing to see here…
