Is something wrong?

I am a big fan of NCH software for the PC. This is my first iPhone app from them. It looks like the app has everything you could need but it just doesnt seem to work. I have the free version and understand I have no editing tools. But when I try to even activate the menu, it doesnt respond properly. Then, when it finally does, and I can select a tool just to see, I get a blank window that pops up and you can not back out of it. Very frustrating free version. Hopefully this is just oversights and will be reconfigured in future versions. Im afraid to pay for fear that the problems will remain even in the pay version.
