drad+and+drop+in+attachments+not+working

earlier i was able to drag files like excel word image or zip/rar from my windows explorer window to emclient new compose window… suddenly it stopped working and now i am forced to seek file through attachemtns link… please advise wht to do to get drag and drop working again… on the contrary i can still use .eml file drag and drop… just not other files… i am using a 64bit version of windows now compared to previous 32 bit version… 

Hello Hirak,
which version of eM Client are you running? (check Help > About to find out) Which Operation system are you using? When you try to drag and drop the attachment, does an error message pop up?

Best regards,
Olivia
