Is it just me, or there is someone with a similar problem like this one? When I open a .7z archive with the 7-Zip File Manager and click the "Add" button, I get this: but if I right-click any file and choose to add it to the same archive, there is no problem. If it makes any difference, I always use the LZMA - Ultra compression method. I am using 9.13 Beta, but previously I had the stable 4.65 and it was the same thing.
