Fixed: I appears as if I all of a sudden have to click-and-hold to get it to appear.
Why this is needed all of a sudden is beyond me.
Have you tried using the Clear button on the Options bar? (A counter clockwise arrow).
Have you tried resetting the Crop tool (left end of Options bar)?
Otherwise, what operating system? And is this with the Ratio, Overlay, and options (the Cog icon)?
Glad you got it fixed. Was the system busy and working more slowly at the time?
No the CPU load was less than 15%.
And thank you very much for replying - much appreciated!
