Error with Zip files

I am a very happy customer, and I think the program is a godsend, but for the past few months it hasn't worked to extract zip files using Windows' own extraction (“extract all” in the file explorer).

The workaround for me would install the 7-zip and use that to unzip the files.

A bit inconvenient but it defeats the purpose of having your wonderful program. The current version and the beta version both suffer from this, and this is with default settings.
