The "F" full screen problem is BACK
I had to revert to Lightroom 6.1.1 because the latest update not only messed up with the import function but also brought back the "F" problem that was resolved in 6.1.1. If you are using the Spot Removal and type F to get to the full screen mode, well you are going to stay in this mode for ever, unless you get out of Lightroom and start again. What a pity!!
