I bought PSTF (because to this day, I'm stupid enough to buy shareware before testing it fully), and I'm disgusted with it. Not only did it screw up some of my tray icons (especially Vuze) by making two, three, four, or even more duplicate icons appear erroneously, it has proven useless for restoring icons after an Explorer kill or crash. That sucks, because icon restoration is the main reason I bought the damned thing.
I sent two emails to "support" (first one sent 8 days before today) and have been completely ignored.
I don't need to hear "Works great for me; you must suck!" from 15 other people. Really. (No need to copy/paste that sentence to be cute, either.)
I fully admit the loss of cash is my fault. I never learn. Oh well. I'll find a way to make it up.
