pixel persona brush not painting on empty pixel layer

[gw_westdale]

In Photo, if I create a new pixel layer, I get a transparent canvas on which I can start painting leaving any layer underneath visble where I have not painted.

In Designer pixel persona Windows 10 V1.9  a brush will not paint on a new (ie transparent) layer.
Filling the layer with white enables me to paint - but obviously  kills the aim of being able to see the layers underneath.
A transparent area created by erasing paint after filling with white also does not allow painting so that is not a workaround.
Still true if I rasterise the layer.

Is there a workaround or is this a bug or misfeature?

It works fine for me, @gw_westdale.

Can you provide a screenshot of the problem, or (even better) a sample .afdesign document that demonstrates it?

By the way, in Photo you start out with an empty canvas. If you select the Brush Tool and start painting, then if you have the Assistant Manager properly configured it will create a pixel layer for you to paint on. But without having a pixel layer you cannot paint with the Brush Tool. The same applies in Designer, in the Pixel Persona, with the Pixel Tool or the Brush Tool. You need a pixel layer to paint on. Are you sure you have one?

This works in Pixel Persona

You need to switch off "Protect Alpha" in the context toolbar for the brush

Absolutely right  -- I have no idea how that turned on but that is the problem ... many thanks - I had tried all sorts

edit : I think it's down to accidentally selecting a brush that sets 'protect' on,   then choosing  the brush I intended to use, which does not set 'protect' but leaves it on.
the 'leave the setting alone' type of brush is a hazard I'll have to watch out for !

I was just able to fix this problem after several frustrating days of not getting anything done. The Protect Alpha feature was turned on, probably from the time I was working on Quick FX to add inner or outer glow, and protect alpha makes a difference on how it behaves, so I had it turned on for some of what I was doing. Apparently you have to turn it back off again when you go on to something new. Glad I found this thread, thanks!

Please, tell me how to find this "protect alpha" and switch it off forever.
I hate it, I don't use it, I can't see it on any tool context toolbar, I never wanted to see it / use it - whatever. 
It cost me several days of frustration and anger as it blocked new empty layer edition.
I don't now how to edit this context tool bar when I use tools like brush, clone tool and I don't know where else this horrible trouble maker exists.
I want to delete it, or if not, I want to delete this soft and get my money back. Enough of time wasting.
In tutorial info to turn it off means nothing if you have no idea where this tool exists.
Sorry, but I'm furious.

You can't.

You can't modify the content of the Context Toolbar, either. It is determined by the tool you're using. 

You haven't said which application you're using, and which tool. The option is primarily on the "Brush" Tools (any that are named something Brush Tool, and if you can't see it in the Context Toolbar perhaps the bar is wider than your application window or your screen. In that case, you might have a chevron icon (>>) on the right edge of the Context Toolbar, which you can click to expose the hidden options. 

Or, perhaps the Tool you're using doesn't expose the option, but we'd need to know which tool you're using when you have the problem.

The clone tool does not have a protect alpha setting, so whatever problem you have using that tool it is unlikely to have anything to do with protect alpha
