Automatic print promt while previewing pdf

Hey dear fellow users,

the following thing only happens with attached pdf files sent from a certain sender:

When I hover my mouse over the attached pdf files to preview them, instead of the preview popping up I get directly sent to the print window of my system. So I guess it’s connected to those pdf files from that specific sender and maybe some settings they got activated, which automatically trigger the print window to open.

Anyone else ever had this issue and maybe knows how to deactivate it? It’s kind of annoying that every time you just hover your mouse over the attachement, this happens.

I’m using the latest version of eM Client (10.1.4588) and run it on Windows 10.

Thanks!
