I can't mark in checkboxes on some websites with my mouse
When working on my MacBook Pro sometimes I cannot mark in checkboxes with my mouse on some websites especially from the government but the weird thing is I can type in the boxes. I've tried different browsers like Safari, Chrome, and Firefox. Why is this and what can I do about it?
MacBook Pro (Retina, 13-inch, Late 2013), OS X Yosemite (10.10.5)
