Weird - No Checkboxes?

[PinStripe]

I just installed this OS on a Dell pc and when I went to download a file and open it
with a certain program, it offered the typical selections, though no checkboxes to
select any of the options. How do you select any option?

I am attaching a screenshot:

Here is another one... this is system wide! NO checkboxes- Cannot select anything.

Wow... this isn't the only thing I'm finding to be a problem on this OS...
I can't even download a music file and can't select the program to play it in
either. I think I am DONE with this distro! Too many issues.

This looks like a broken GTK Theme. Please make sure to check if you change it in systemsettings and restart the application that it works.
