Perfect! I had looked all options but I didn't find it!
Thanks

Do you have Tools > Options > Library > Metadata Lookup > When Viewing Lyrics checked?
If so, uncheck and try again

I have a simple problem but I'm not sure if is possible to solve: When I enter in the File Properties and select the panel Lyrics, if lyrics are missing, the software freeze for several seconds until it finds some results or anything, because the search of the lyrics start automatically.
Is there any possibility to change this option so to have the search that starts only if I request it?
Frequently I need to paste the lyrics copied from another place and I'm obliged to wait several seconds.
