Unable to delete attachement after sending email from PC

I am using Pro license version 8 for the last few months. I got an update few days back and after update of my em Client I am facing an issue that whatever file I am attaching in email which is sent properly but I am not able to delete that file from my PC, its showing that the file is opened in em Client. Also note this was not happening before the last update. I need to close the application to delete that file every time which is like headache.

Yes, I noticed that myself in the past few days. It is an old problem that seems to have resurfaced. Sorry Meith.

As a Pro License user you can open a support ticket directly with eM Client. They may have an unreleased newer version where it has already been fixed, otherwise keep checking the Release History for any new version.
