Filetype changed on its own

[dsuden]

I had a flash video (downloaded with UberTuber) sitting on my desktop, and then deleted it, so it was no longer on the desktop. Later that day, I saved a text file from Pe to the desktop. I didn't look at it at the time, but this morning I noticed my text document had the same icon as the flash video I had trashed. I was able to use filetypes to change the document back to a text file, which allowed it to again be opened normally in Pe, and its text looked fine. But that seemed like a strange enough turn-of-events that I thought I'd better report it. Note, the trashed video file also had a completely different filename than the text file on the desktop.
