Hi,

it's me again; just now I dimly remembered that in an entirely different 
context someone was advised to try to change the USB port.

So, without much hope, I changed the card reader from the top front socket to 
the bottom front socket - and everything appears to work perfectly!

I copied six files - two archives, two jpegs and two texts - to each of the 
seven directories mentioned in my original message; the Palm can handle each of 
those 42 copies without the slightest problem.

Can any of the experts explain this to me, please? 

(And must I now expect problems from my Epson Perfection 1660 Scanner which now 
is plugged into the top? Until now it never gasve me a single bit of trouble.)

Regards,

Jochen
