Something I recently started seeing: when in Safari, specifically browsing my Google Drive directory, I click from folder into folder onto files... One out of two clicks don't open the folder or file - in fact nothing is even highlighted. Refreshing the page solves the issue... until a few moments later it starts failing again. So, hovering my mouse doesn't evoque a clickable link anymore. So far I only see it when working in my Google Drive directory. Doing the same in Chrome, no problem at all. Any idea's anyone?
