Moving this discussion to the Photoshop forum.
Making a quick stab here but is there any chance you happen to be on a layer where the lasso or eraser tool cannot do anything? (E.g., an adjustment layer). Can't tell you the number of times that has bit me.
One clue for this is that rather than see the normal cursor, you get a "null" symbol (the circle with a line through it).
Please let us know if this is the problem. Otherwise, can you provide more detail as to what you see when you are trying to use these tools. And, while this may not have anything that can help with this issue, providing your OS and verifying which version of PS you are using might be of assistance.
Thanks so much for your reply. That is a good guess but it's not the case - I am always on regular layers, and other similar tools continue to work (like the magic wand or the box selection tool). I have also made sure to deselect everything just in case I unknowingly selected something and can't use the tool because I'm outside the selection.
When the tools stop working, I still see the icons as my cursor the way I would if they were working, except nothing happens when I try to use them (for the lasso, the 'marching ants' selection line does not show up, or nothing erases when I use the eraser). I am using Photoshop CC on a 2017 iMac running macOS Sierra. Any other ideas?
I've also had some "stupid photoshop tricks" events, not this but there's times when a brush just doesn't seem to want to work.
Have you tried quitting and restarting PS? Restarting your computer? Have you tried resetting your PS's preferences? I'd suggest trying those in that order (from least to most time intensive) and seeing if any of these have any effect.
Please let us now if this does it for you or not.
I also have the issue with the eraser tool. I've restarted it and used all updates. The eraser tool still doesn't work.
Oops. Just got it to work. Check the opacity on your eraser brush. Mine ended up at 2 percent. I updated it to 100 percent, and it now works.
Check the opacity of the brush on your eraser. Mine was at 2 percent. I changed it to 100 percent, and it now works.
Unfortunately, the opacity isn't the issue for me. It's on 100% opacity, and it's more than just the eraser tool - it's the lasso, eraser, and the clone brush all at the same time. It's driving me crazy! I'm glad you found a solution for your problem, though - thanks so much for jumping in to help!
I'm so sorry for the delayed response - I missed your post somehow! Thank you so much for your replies. I have tried restarting photoshop as well as my computer - sometimes it works, sometimes it doesn't. Which preferences would you recommend I try changing? I'll try anything at this point!
I did some googling and it seems like Wacom tablet drivers can sometimes cause bugs in Creative Suite CC - have you heard anything about that? I need to use a Wacom in my work, so I'm hoping there is a workaround.
On a related note, do Adobe administrators ever weight in on these forums? It's impossible to find a helpdesk contact number for them; they just direct you to these forums. It seems like it's a deeper issue with CC that they could help address (I have had issues with InDesign as well since switching to CC) but I have no idea how to get a hold of a real person over there. It's infuriating that they had a product that worked practically flawlessly for decades and now they've forced conversion to CC which is just totally overrun with glitches like this and we are all just left trying to fend for ourselves to find a solution. End rant! Anyway, if anyone from Adobe is out there (or anyone knows how to contact them), I could use your help!
Sorry but I left for holiday and am away from my computer. Yes, occasionally Adobe people wander through here but not on a regular basis. I wish I could help sooner but I can’t. Good luck!
I have same issue. I have updated Photoshop CC and also use Wacom. It does randomly and then none of the tool appears to work. However in history it shows that tool has been used.
It nuances to start Photoshop every-time
, while you are working the file.
Any help from Adobe?
