Why does the Mouse cursor change into a black box within Adobe DC?

[Guest]

We have a user, who when opening any pdf document, her cursor changes into a black box

When you go into the preference settings it shows normal, when back into the home screen black box cursor returns

Removed Adobe DC, Reinstalled again Via Web Installer

Updated Java in-case it maybe linked

Restored the OS to a previous working state and the it still does the same

Is there some setting that could be causing this? Macro or ActiveX?

Black Box only shows in Adobe

This just happened to me today. I followed the instructions, closed Acrobat and deleted the files, relaunched DC and the black box is gone.

I just deleted the file and that did not help solve the "black square" mystery. I have never seen this problem before. Like many of the fellows in the community, I probably received an update and now it all jacked up. What should I do?

WORKED FOR ME

When I browsed the suggested directory, I found two IconCacheRdr files.  I deleted the one with the latest date, IconCacehRdr5536.dat, and left the earlier one, and that has cured my cursor of the black pox.

That worked perfectly! Thank you.

I am having this same problem. Deleted the icon file (Acrobat closed) and still get the annoying black box.

Reset my computer. Have tried this solution several times with several scenarios.

It's awful. Any other solutions?

Noticed that this is only happening when I am connected remotely to my computer. Black box is not there when I am sitting at the computer. Any ideas what might be causing this? It only happens with Adobe.

Remote connection program is ScreenConnect.

Has there been any more update to this? 

Is it only happening to Mac users who log in remotely. 

we have deleted the files you guys say to delete and made the black box bug file- done everything and this stupid balck box is still there!!

Wow. I posted this problem in 2021. Today is October 23, 2023, and still no solution. 

Certainly Adobe can fix this problem that seems to effect so many.

I found the IconCacheAcro65536.dat file in a different folder. Instead of being in the DC folder it was in 2020. C:\Users\<user name>\AppData\Local\Adobe\Acrobat\2020

i was facing the same problem before and got the solution.

step 1- open  " C:\Users\*your user name*\AppData\Local "

step 2- you will find a folder of "Adobe"

step 3- delete the folder " Adobe" (don't worry your data will not be deleted)

step4- now open your pdf file.
