CAS bug when calculating sum(1/n,n,1,medium_value)

I tried your calculations you proposed, but I can't confirm your observations. In all three cases the results appears very fast. My calc is a prime g2.

Indeed, I now have trouble reproducing this on the G1, but on the G2, I still face the same issue.
It seems that it's a good idea to turn off the HP Prime before attempting this.
Try again using the method provided below (a few additional steps).

• enter CAS [CAS]
• clear the history [Shirt+Esc]
• turn off the Prime [Shift+On]
• turn on it again [On]
• perform soft reset [On+Symb]
• you should be in CAS already (if not, something went wrong)
• input the sum using the [Units] key for (1/x) from x=1 to 2000 and execute for the numeric value using [Shift+Enter] => the result will appear within about 1 second;
  result: 8.17836810361
• copy input from history and change the range: from 1 to 2000000 and run again [Short+Enter] => the result will appear immediately;
  result: 15.0858736534
• copy the first input from the history (for range from 1 to 2000), and run again [Shift+Enter] => this time you'll wait for the result for several minutes...
  

Please let me know if you were able to reproduce this issue.
Thanks.
