Files lock up after being attached in eMclient

When I attach a .pdf file to eM Client, it locks up the file afterwards, so I cannot delete it, redo my scan to that name or anything else.
I either have to shut down eM Client or the computer to make the file available again.
This never used to be a problem till after the last update.

Make sure you have the PDF closed before attaching the file to eM Client.

The issue has already been addressed, and a fix will be in the next release.

It is not a problem of an open file. It is a scanned file that was saved to a folder, and when it is attached to eM Client, it locks up the file in the folder so a scan with the same name can not be saved. It never was a problem with the old version.
