... but with 98se the 'open with' could be edited or deleted from....
Windows Explorer - View - Folder Options - File Types
Look for your Photoshop entries and see if any of them are linked to your USB. Bit strange why it picked on a Program to open it with when it should be linked to Explorer as far as I know. I can't afford to upgrade to XP so I remain in the dark about this.

See detailed query on XP os forum. The problem occurred after installing Photoshop essentials 3--When I inserted my flash memory stick xp came up with a query page asking whetherni wanted it to open with essentials 3 --I checked yes and then realized that the form box said "always". I have had all sorts of usb trouble since and wish to know if I can revoke the "always open with" designation.???
