Disinfotainment

I was horrified by an obscure bug I discovered when I was working in Photoshop the other day. I opened Photoshop, created a new file, and when I saved it, the default folder where I had last saved files was open, and I just hit return like always. Then I stopped to think, hey wait a minute, I just threw that folder in the Trash! So I looked in the trash, and indeed, inside the trashed folder, there was my newly created Photoshop file. I pulled it out and saved it in a safe place.
This is not how an Open/Save dialog box is supposed to work. Yes, it's supposed to remember the folder you last saved to, as a matter of convenience. But MacOS X apps should never save files into the Trash. It just does not make sense.
Update: Thanks to Vince Mease, I discovered that this bug is not at the OS level, it does not occur with Apple applications, only 3rd party apps. Apple's apps work correctly, but many non-Apple programs do not understand that you aren't supposed to save to hidden folders like .Trash
