Bugs in Finder?

Has anyone else been noticing some weird behavior by Finder? I was just trying to delete a file, so I hit cmd-Delete after having selected the file. After a lag of 3 seconds, I heard the trash "click" noise, and the column-view window I was in poped back to a completely different folder. When used the back button to get back to the folder I was in, the file was still there. Dragging that icon into Terminal, I got a path for the trash... so I rm -r 'ed it, and closed the window. When I got navigated back to the folder, the alias I had created, to get to it from another folder on another drive, was gone...

This is just one of a series of weirdnesses I have experienced...
