I use patch tool for skin retouching and every time that I overlook very small selection that I left (I think it's 1 pix) and after it I start liquify filter - Photoshop stops working and closes without saving the results
Thank you Jeffrey, but first time I saw this bug I went for help, did all this recommendations and still no result. Please try to select 1px and after that launch liquify tool. I have that error every time. Do you have the same?
