Image -> Adjustments -> Curves troubleshooting

[default0duzdf0ihu2q]

Product is PS CS6 Extended Win ESD running on Win 10.  Installation date was in 2013.  The Image -> Adjustment -> Curves  action has stopped working correctly.

When I execute the Curves action and get the Curves dialog window, the cursor always changes to the Color Sample tool tip and I can’t drag the Curve up or down.

Try this; Reset the preferences:
Press Ctrl-K
Click on "Reset Preferences on Quit" in the "General" tab and press OK to confirm.
Press OK to close the Preferences window.
Restart Photoshop.
...or, give CC 2020 a chance! 🙂

I have no "Reset Preferences on Quit" under the "General" tab.

Press the Alt key to get the reset to show.

I don't understand when I should press the Alt key???

Here's a pic of my workspace....................When I place my cursor in the dialog box, it automatically becomes the color sampler tooltip.

Please share a screen capture of your workspace showing the issue. This should help people see what might be happening. Also, as suggested, perhaps resetting your preferences may help.
