Can't drag photos directly from Whatsapp Desktop onto Macmail anymore

Hay guys,

I am hoping someone can help me out with this! I use Whatsapp Desktop for work and have to drag photos from whatsapp onto the clients email, It hasn't allowed me to do it since the update before this current one. It's driving me crazy as i now need to make folders on the laptop then drag onto email but its slowing my work down dramatically. Can anyone help me figure out how to fix this glitch?
