[power-pro] PP and MainType?

[Brother Gabriel-Marie]

Hello, y'all!  Does anyone in this forum use High Logic's font-viewing
program called Maintype?  Whenever this program is open then certain of
my PP bars (in particular, the one I use in InDesign) go on the fritz
and lock up.  As soon as I exit Maintype, all goes back to normal. 
Sometimes other PP bars lock up too.  It only happens with this one
program.  Has anyone experienced this besides me?
