Drop dpwn box isnt hightlighting when I go to edit something, Please help

I have used Audacity for many years and I’ve just installed it on my new laptop which is Windows 10 fully operational but I when I go to edit something say like a vocal recording the drop down box isn’t highlighting Audacity at all

Which version of Audacity? (look in “Help menu > About Audacity”)

Are you referring to an audio file, or a track in an Audacity project, or something else?

Which dropdown box?
