Confirmed! I can reproduce this on Vista 32-bit. I've got a feeling about what may be causing it and I'll talk to GPSoft about getting it fixed.
(Wow, I forgot how small and slow floppies were. "I'll just copy this file here as a text... oh wait, that's bigger than would fit on the floppy even if it was empty." )
Go to Preferences - File Operations - Copying Files and set the Buffer Size at the bottom to 2048 KB. That's larger than any file that will fit on a floppy and it will ensure that files copied to the floppy will be written in one go, instead of in several chunks.
When files are copied to a floppy in a single write the problem seems to go away.
i don't know if anyone else is having this, but i'm experiencing the similar problem, but only if moving a file from source local drive to dest network drive. i tried changing the buffer as above, but that only seems to work for files smaller than the buffer (which for me caps at 9999)..
