LEIF HEFLIN Pretty much every error that could occur is now displayed within Ez7z, therefore the log is now not necessary for most operations. It's still being created just not displayed, except for PAR2 repairing/verifying and when it comes across a file with a ' in it.
If you still want to look at it just right-click on Ez7z in the finder and click "Show Package Contents", then "Contents", "Resources", and open "tempLog.txt". Ez7z delete's this file when you quit, so you'll have to do it while it's still open.
