I echo everyone elses comments about Tonto, but I have much more pressing reason. There are several threads describing a bug with ProntoEdit that causes it to crash on some CCF files with "learned" IR codes. I havn't been able to edit my primary CCF with ProntoEdit apart from the first couple of days that I was building it. It's not that big, complicated, or stylish, and only has pretty standard devices in it, but ProntoEdit will not touch it!

So it's Tonto for me from now on, and besides, I think it's a better "product" anyway.
