Especially, I'd like to tar and feather the guy who invented the file-replacement technique on save. Thanks to him, each time you save your document, you break every positioning you had applied to "its" icon.

Ho, and absolute paths as file references, geeee !!!
For example, put an application in your start-up list in System Preferences. Ok, now, move it (imagine it still was in your download folder when you decided to keep it at startup). OK, now it won't launch at startup. Many cases like this.

Here are my the worse annoyance of all. I'm not stuck to OS 9, I'm just bashing at not well-done software. And I'm afraid it will stay there........ forever....... cos' now people got used to it......... not so bad.... workarounds.... column view.... HAAAAAA !
