Perspective crop tool error

[ikonmina]

Since the last Photoshop update (25.1) a few days ago the perspective crop tool does not work corrcetly. When used, the result is a single pixel (yes, hard to see). I can use perspective warp but I find the crop tool eaier to use.

Sorry, just after I posted my query I found the answer...the width was set to 1 px. I deleted this and the issue seems to be resolved.
