I feel that this is getting worse... or its my patience that have run out completely with this.
After using the "Alt/Opt" button while grabbing and slide the slider it is always latched on next time i hover over a slider and nudge/step it with the keyboard arrows. Seems fine if i grab the slider again but if i do as described above the screen flashes over to the "Alt/Opt" View. I'm not able to get rid of it any longer either so its terrible annoying. Feel like it slows up the computer as well as the screen flashes views as well as it is terrible annoying to wait for the screen to go back to normal to see the result...
Anyone else experience this and hopefully have a fix for it?
You more than likely have a problem with your keyboard. Try a different keyboard and if it is a notebook just connect a different keyboard and test.
There is nothing in LR that would Lock the Alt or Option keys. Check the setting on your Mac for some type of Accessibility setting that could cause this.
it is not the keyboard as it is not all functions in Lightroom that act this way. If you hold Alt/Opt the sliders and some other buttons will change to "reset" and that is not the case. When I have this problem I can still push the Alt/opt button without doing anything else and see the functions toggle between normal and reset so in that aspect Lightroom does not think the alt/opt button is pressed but if I nudge a slider it acts like it is. And as I mentioned same on both the iMac and MacBook.
