Whenever I use this app, it creates a gmon.out file in the root of my HD. It took a while to pin it down to SQL4X Manager J - every once in a while, I'd notice the file and wonder how it got there. Today I finally figured it out. (I'm not sure, but I think this used to happen with 2.9 too.)

Anyway, I did a bit of Googling, and it turns out that this is the profile file resulting from compiling using gcc with debugging options turned on. I'd guess the developer didn't set his compiler flags correctly to create the shipping executable.

Otherwise, I find this app quite useful (though the UI's a bit weird in spots).
