BRANDON MOL  It may be crashing on your system, but it isn't because of 10.6

Version 1.5.3 runs on both Leopard and Snow Leopard just fine. I am not saying you don't have a problem, just that it isn't because of 10.6.

What exactly is the problem and/or error message? Try version 1.5.4+ and if you still have the problem, please let me know. I made some significant changes in 1.5.4, particularly in the area of support for other locales. In 1.5.3 and older, the software would reference playlists b name , ie: "Movies" which is not the case for systems running with locales other than English (US) or English (Canada) . This should be fixed now, amoung other things.

PJHOT  Had previous versions. I think I've been using it almost since the beginning and it has ALWAYS worked as advertised & flawlessly.

I'm downloading the 1.5.4 update now.  
(Version 1.5.4)

PJHOT  Still no luck. Analyzing entire library generates an error window & a hang. Analyzing a selected playlist applies about half of the results before a hang. :( None of this happened until I installed 10.6 and continued through the latest iTunes update.

PERSON1229  I'd be interested to hear how MacDust did this. Because I'm positive it didn't.

Open your Safari Preferences, Click the Security tab (the lock picture), and check what you've got your Accept Cookies setting set to.

PJHOT  Uhhh, yeah it did!

I kept going into the security tab and changing the pref, then restarting Safari.

The only way I was able to solve this issue was to back up my bookmarks and delete all system files related to Safari.

What a headache you've caused me!

CABERLIN  Works nicely here on Leopard. No problems at all. Maybe there's something wrong or outdated with your computer?
