Vipir,
Your issues with Adobe are not limited to 10.4.6. An interesting two paragraph anonymous report from Macintouch below Todd Novak and Henry Bonath:
http://www.macintouch.com/readerreports/macosx1046/index.html#apr07
"There have been reports, from Geordie Korper from Group Logic and others, claiming that Adobe Photoshop CS2 (Version 9.0) will crash occurs when using Mac OS X 10.4.6 when saving to an AFP server such as Mac OS X Server, Microsoft Services for Macintosh (SFM) or ExtremeZ-IP.
I have been running Mac OS X 10.4.6 for weeks (I have access to developer seeds), have opened and saved Photoshop CS2 documents from a Mac OS X Server system numerous times, and have never had Photoshop crash. So it's not a problem endemic to all installations of 10.4.6.
My experience with Adobe applications is that they have never been reliable when opening and saving documents from and to a server. While not often crashing the application, I've seen numerous instances where working with an Adobe document stored on a server had irreparably corrupted the document. This problem dates back several years, even back prior to Mac OS X. My advice to all my users has always been to copy any Adobe documents to their local workstation before attempting to work with the document, then copy it back to the server for storage."
So as you see, you just happened to have stumbled upon this random behavior that others have seen in earlier versions of Adobe and Mac OS. Just took you longer.
