Used to use this every day. Now it's a pile of rubbish. Doesn't record the colour I click on more than 2/3 of the time, records the wrong colour, laggy and slow to respond. Menu options were changed so can no longer copy RGB from first dropdown.... and Copy RGB from the new secondary menu just flat out doesn't work.
What an embarrassment!
Now I'm using Color Picker and recommend everyone to switch to that, it's light, accurate and does exactly what it needs to.
