Hi st87,
Right-click the layer in the Layers panel and select Rasterise then proceed with the selection and deletion of unwanted parts. This is happening because you are probably working with an image layer type (look at the label between parenthesis after the layer's name in the Layers panel).
 
Image layers are a special layer type that retains all the original image data - you can think of them as embedded images -. They are created when you use the Place Image Tool, the File ▸ Place command or when you simply drag them from the Finder (Mac) or File Explorer (Windows) to the canvas of an opened document. They can be transformed globally (rotated, skewed etc) without losing quality but they cannot be edited/manipulated at a pixel level. For that they must be rasterised first as described above.

Oh yeh, that works for me too...
 
Thanks yakk! 

Hi st87
 
If snapping is active, you'll have a little attraction on the edges while moving your cropping frame.

OH, it's all good now! Thanks guys!!!

Sweet! So then there shouldn't be a problem with Serif delivering that DAM software soon. Their announcement to PetaPixel was only a month or so ago. So I guess we have around 6 more months to go until we hear some news about a beta program?

I suppose for the same amount of human resources, you will be diverting your efforts away from research/development of additional features and improvements on the Mac platform because those bodies will be committing time on developing and ironing out whatever kinks there will be on the Windows platform.
Personally, i think it's a good move if we want to see Serif surviving. From what I've seen, besides some minor issues, Affinity Photo is already "quite good". At least for what I need, and especially for the price it asks for. Every Mac user will only typically buy it once. Spending more effort "enhancing" this software is dead money to Serif, unless said enhancement is proven to turn more Mac users towards AP.
The alternative will be Serif running very lean, possibly not even surviving, and we'll lose support for their software entirely. Which will suck, given how often Mac OS changes.
Also, my newest Mac is my Macbook Pro, early 2011 model. It's likely to be my last, because I simply do not agree with Apple's attitude and direction (both hardware and software). Everything is trending towards a more "consumer" and over-simplified feel. Your new Mac Pro looks like a toy, they took away Aperture, no more CD/DVD drives even on desktops...
It's become a numbers game since the death of Steve Jobs. It's no longer about developing nice products, but about culling "low performers" in favor of what is profitable (which is, the general consumer market). What's next on their cull list? Probably Logic as I'd imagine Final Cut Pro will stick around for a bit longer.
After all this, all I'm trying to say is, as much as I hate Windows equally (especially Windows 10), I might (quite unfortunately) be joining the Windows platform very soon. And it'd be nice if Affinity is there to provide some level of familiarity.
 
 

Noted, but I don't actually have LR, I'm just pointing to LR as an example. I'm not planning on buying LR either as Adobe is not getting a cent of my money after they have decided on forcing people to pay a subscription.
Ditto :-)

So I tried affinity photo with my wacom tablet. Sensitivity does not appear to work. I'm guessing that this feature just hasn't been put in yet? Would be really nice to have.
... Or I could just be not setting things right. I did vary the "firmness" from the wacom driver and it didn't seem to make a difference either.
Thanks!
