How do I specify pixels when resizing images?
I just installed my Photoshop Elements 15 to a new computer, and some things I'm used to apparently got reset.
The only unit of measure I use for image sizes is pixels. I can crop an image in pixels by typing "750 px" or whatever into the fields on the cropping tool. But when I then want to resize the image, the dropdown on the image size popup will not show me pixels as an option. Here's what it looks like:

The current size is in pixels, but the new size cannot be specified in pixels.
I went to Edit > Preferences > Units & Rulers to set pixels as the measurement default (that dropdown DOES offer pixels, but it made no difference.
I seem to vaguely recall having this problem long ago, but for years I've been happily resizing in pixels, and I don't know what I did to fix it.
Help?
