Cover will be deleted automatically

Actually, no modified data in the tag panel is saved unless you say so explicitly.
See e.g. here:

Leaving tag panel does not automatically save changes

When I enter tag information, all goes well - no problem. However, if I click on the filename in the right hand window, all the tag info I just entered disappears and I have to start all over again. I can duplicate this over and over again. The only way to make sure it doesn't disappear is to make sure you save it while you're in the tag so that you don't lose it. Depressing. Hopefully in the works for a fix. At least an autosave when clicking off the tag or something.
