Thank you for the report and your STC supplied in another post. One 
thing I have consistently noticed with 5.15.18 using other programs is 
that populating the first open file dialog takes a very long time. It is 
not hanging, but it sure looks like it. Maybe that's the case for you.

I will build your STC and test with it. Regarding your other tests, I 
see Audacious is a Cygwin package but what is LMMS?

If this turns out to be sluggish behavior rather than an outright bug, I 
still might be able to figure out what the root cause is.
Thanks again,

..mark
