I think we had a problem introduced in 10.13 related to cursors that was fixed. Would you mind trying out the latest version? You can get a trial and install it side-by-side with your Camtasia v2, to see if it fixes the problem.
Thank Paul, but following your instructions I installed the trial version of Camatasia 3 and the problem persists. I think TechSimth should review this since there are many people who make tutorials on Photoshop, being in this application very important the change of appearance of the cursors
