yet it works
In trying to set up a routine the instruction asked the a disk be inserted in the optical drive and a line typed into the 'Run'
Having done this I get the drive not recognised warning.
However the CD drive on that letter works perfectly well in all aspects otherwise.

I have done the Admin/Computer management/storage /change driver letter thing
But still I get cant access - even under the new letter.
So what is up?
