Adobe 2023 release 25.0.0; Windows 10.0.19045 Build 19045
Since the latest update, in the Curves dialog box, if I attempt to set the input for the white or black point numerically, if I type a three-digit number (ie., input 249 -> output 255), after I type the first two numbers, the cursor jumps to the beginning of the field (e.g., if I type 249, the entry winds up being 924). To enter the correct value, after entering the first two digits, I have to mouse-click or use the arrow keys to reset the cursor to the correct location, at which point I can type the desired value. This behavior occurs setting the input of both the black & white point, but not the output, and doesn't seem to affect any additional points added to the middle of the curve. Dragging the black and white point sliders also seems to behave normally.
