Cursor in Adobe Photoshop.

For some reason the cursor in Photoshop has gone from a single pointer to a triple one. It makes using it very dificult. No idea how to get it back. Anyone?
For example when using the Crop tool, there are three little boxes side by side instead of one.

any use?

 

DPI has been set to both 149% and 151% with no effect. Thanks for trying.
Odd that the same problem is in all three versions of Photoshop which I have.

 

Is it something simple like num lock on then? I don't know the shortcuts

 

So far I can only see stuff about font size. Try changing your system font size to medium, if its on something other than that.

 

Num lock has been both on and off as a test.

 

If I adjust the DPI to 100% then the three cursor problem goes, HOWEVER, I can then no longer read anything on the screen. Any other setting has no effect.
Wonder why it has suddenly happened too. Everything worked properly until a few days ago and as far as I know we have altered nothing.

 

I think there are ways of resetting , but this may not be ideal for you.
If I see anything else on the net, I will let you know

 

What version are you using? Maybe you change the font size here (preferences), then restart PS?

Elements 9, PS7 and CS 3, all old stuff I know, but they worked up to now.
I have looked at the Preferences thing before, it makes no difference.
On all the sites I have been to, this question is almost always in the Unanswered category.
Thank-you again for trying.

 

set dpi font size to 120dpi
