I've been using the Adjustment Brush in LrC and have found that it usually only works once and then, when I go back to use it again, it doesn't function. I've been through all previous posts in the support community regarding this problem and checked that settings haven't changed but that has not been the problem. I've had to close LrC and then reopen it in order for the Adj. Brush to reset.
I've even tried clicking on Reset at the bottom of the Adj. Brush panel to no avail.
Has anybody elese had this problem and if so, any idea how to resolve it?
Since I posted this query I received both a new update from Adobe Lr and Apple. I couldn't find what the Adobe Lr update actually changed as I'm already on 9.3. I updated the ios from Apple today which required a reboot.
I started taking screen shots to show you what was happening and now, happily, I haven't been able to recreate the problem. It appears it has been resolved.
If it happens again I'll show you. What I meant by 'it doesn't function' is that even though I clicked on the adjustment brush it's as though that option didn't exist even though I'd selected it.
