Comment 4 for bug 1637353

I cannot replicate this on my Win10 machine with calibre 2.70. Steps I
tried:

1) Click Edit Metadata
2) Click Download cover
3) Right click one of the downloaded covers and select "View at ful
size"
4) Click Save as
5) Browse to the pictures folder on my computer
6) Type the filename test.jpeg
7) Click OK
8) The file test.jpeg is created in the folder with the cover image

The only thing I can think of is that the folder you are trying to save
to is readonly or you dont have permissions to modify it.
