Scrolling down to "click here to download" allowed downloading these without a problem. However the usual "extract" option in the pop up menu does not appear. If the OS matters, this is on Linux Mint Mate 18.3 Sylvia.
The "extract here" option still does not appear for the two zip files as noted above. I tried opening a different zip and the "extract here" option shows. Is it maybe a permissions thing 'cause you be the boss?
Clarification: I deleted the first two downloads. Then downloaded a second time. The second try downloads just fine, though I still cannot extract either.
First, I am supper happy that a fellow missoulian not only uses mint, but is on the exact same version as I am. Next, when getting screen shots, I tend to press alt-printScreen - and linux takes a pic of the current window.
I guess my test is that I simply double click on the zip file. It shows me the list of what is in it. My impression is that it is not doing that for you. I guess mine is set up that double click means "open with archive manager".
When I right click on the zip file, the first option is "open with archive manager". In yours it says "open". (dramatic music goes here)
I confess that I don't fiddle with mint much. I spend 99% of my time in browsers. Is it possible that you are using a different zip tool than I am?
