When multiple files are selected in Explorer and I try to hash them with the "Hash with Hashtools" right click menu entry, only one file is added. The rest are ignored. If the program is already open and a file is right clicked trying to add it to the list from Explorer, nothing happens. This problem is present with, at least, Hashtools 4.5.1 and the previous version. I believe this started happening when the update to .Net 6 was issued.
