Every time I save a file it creates a new folder

Question

Hi,
weird problem, never occurred on other Macs. I have a preso and every time I save it I see an Expander application running which creates a new folder file. Let's say I have a preso called Effects.key, when I save it or in auto-save it creates Effects.key folder,   Effects.key folder 1,  Effects.key folder 2,  Effects.key folder 3......an on and on and on....
What's happening ?
Thanks in advance
