IOWAPIPE  I am not so sure this is compatible with Safari 4 (not the beta). I have been running S4 for two days now and several times the app has crashed, complaining about coolIris (once directly in a window) and a couple times in the logfile. I just thought I would write this comment and see if others had similar thoughts.  
(Version 1.10.1)

IOWAPIPE  This is a nice app for what it does. Clean and fast. The one I go to first unless I need a more advanced package.  
(Version 0.3)

IOWAPIPE  I really can't review this app as it seems to freeze up quite a bit. I prefer iSFV or checkSum+. They work.  
(Version 2.0.1)

IOWAPIPE  Works well, although a bit slow. The buttons could also use labels. This isn't my app of choice due to the lack of speed issue, but it works just fine.  
(Version 1.2)

IOWAPIPE  Of the various programs I have tried this comes in as my #2 choice. It is slightly slower than iSFV, and much faster than SuperSFV. (macsfv locks up) The interface is clean.
