Question:...my copy of coorecorder recently stopped showing numbers associated with ring width measurments. That is, I click on the ring, and the appropriate + mark appears, but there is no number with it. The crack markers, and the two markers per ring function also do not have any numbers. Any suggestions?
Probably you have by accident touched the N-key that is bound to the command
Settings/Display settings/Data point and numbers/Show dat point numbers (Keyboard command=N)
Either check the box as shown in the picture below, or just click again on the N-key!
