Funny effect with this version with memory sticks (previous version 
worked fine).

Insert stick, go to Drives and click "refresh removable media" to get 
ECS to  "see" it.

In the previous version this works fine and an icon for J: (the single 
DFSEE created artition) comes up.

In v179
a) it triggers a desktop refresh (bizarre)
b) jams the system

This is on my T61 and the stick is a sony.

Please let me know what info you would like (may not be easy to 
collect!)
