instead of simply deselecting those areas, it is also taking the pixels/image as well.
You seem to have non-committed content then, like when you move pixels with an active Selection.
Hi there! Thanks for your response. Could you be more specific? I googled "non-committed content," but nothing comes up. Is this a new photoshop term I don't know about?
The type was a merged layer, rasterized into simple black pixels, no longer editable as type, only image, if that helps. (Like flat image, don't let the fact that it's type confuse what I mean.) I just used it as an example, though my problem persists even if I draw a black square and select it, then try to deselect a portion of it.
After you loaded the Selection could you inadvertently have moved the content?
Hi there! Thanks for your response. Could you be more specific?
When one selects part of a Layer for example and moves it subtracting from the Selection will remove the pixels.
Select another Layer to break the connection.
I've messed around with it for quite a while. Definitely no movement of anything. Just simple attempts to deselect using the option key with the lasso tool. One of the most basic photoshop procedures that exists. This happens when all selection tools are used. Rectangular Marquee, Lasso, Polygonal Lasso, etc.
I'm actually beginning to think it's definitely a computer problem. I can switch layers, and the problem goes away for a few seconds. I can try to deselect while I'm off the layer, and at some point the problem happens again. I then can go back to the layer, deselect, and the problem is fixed. Then I come over to this site to look at our conversation, and when I return, the problem is back. On top of that all, my polygon lasso tool is no longer available from the dropdown.
I just restarted photoshop for a second time, and at the moment, everything seems to be working.
Thanks again for your help, though.
When truly unexplainable things happen in Photoshop restoring Preferences after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved might be a good starting point:
If it happens again could you please post screenshots with the pertinent Panels visible?
