So then create an empty tab, and close it when the tab is moved

I tried to make a screenshot of the progress, but Im on linux and it should be clear. Drag the tab from one window to another. If the tabs aren't visible, use the ⌘T technique from jdselStrother's answer

Tabs can be visible with just one tab open. Then my method works. But then again, that is for Chrome (on Mac OS X)

You can also drag-n-drop the file into the terminal window, instead of typing the directory/filename. This also corrects automatically the optional spaces in the filename

You can try something from this answer and a bash script in a While True loop, including sleep 600 for the 10 minute delay

Okay. Than it isn't solvable this way indeed. I won't delete it though, as it will work 99% of the tjme

Pinging is related, but not a definite solution in case pinging works. But if you get timeout errors, you know something is wrong. Server-side or client site, but you can rule out the last one by pinging google. If that works fine, the server is indeed busy. Give it a couple of hours, let it run overnight or try again tomorrow. Everyone is downloading it right now
