MPLAB X v5.10 'Power target circuit from ICD 3' doesn't work

Hello,
 
Does anybody know how to fix this issue?
 
I enable 'power target circuit from ICD 3' from project properties -> ICD 3 -> Option categories: power.
 
But it always gives me below information.
 
Connecting to MPLAB ICD 3...
Currently loaded firmware on ICD 3
Firmware Suite Version.....01.54.00
Firmware type..............PIC32MX
Target device was not found (could not detect target voltage VDD). You must connect to a target device to use ICD3.
 
This option works fine in MPLAB X v3.**.
 
Thanks.

    Just noticed the same myself; trying to program a PIC18F14K22, behaving as though target power was turned off although it was certainly on in project options.  Programmed fine with external power to the target.  And then programming a PIC32MX, the opposite - it said target power was on, although it was turned off in project options.
     
    I did have multiple projects open; on closing all projects and then re-opening the PIC18 one, target power option worked correctly again.  I generally have external power available anyway so I didn't pursue the issue further.
     
    Still using 5.10 until I see any great advantage in changing to 5.15.

    MPLABX does not seem to activate programmer power settings as soon as you change them, like MPLAB8 does.
    Often you have to exit MPLABX and start it again after changing a power setting before it activates.

     I have three projects open, two on ICD3 (one's a bootloader) and one on PICkit3.  Hold in reset doesn't help here.  Every PICkit3 operation says 'Programmer to target power is enabled - VDD = 5.000000 volts.' although it is most certainly turned off in project properties (for all three projects).
    Just tried restarting MPLABX with only one project open - the power setting is still stuck at whatever it was at when mplabx was restarted. 
    Closing and reopening just the project (leaving mplabx running) does update the power setting.  
    Guess this is a new feature for 5.10, not tried 5.15 yet (super-slow office internet).

    To follow up my own post (sorry)...
    Same issue in 5.25.  I notice that you can double click 'Unlimited BP (S/W): ' setting in the Dashboard, to toggle that setting on and off.  When you do, it actually updates the power setting as well!  Which is easier than closing and opening the project.  (This is with ICD3 in MPLABx 5.25 using this time a PIC24HJ128G506A but I believe it's the same for all tools and microcontrollers).
    So Microchip, apart from fixing the 'power setting doesn't update' issue, how about adding a similar toggle-able setting in the Dashboard for programmer power?
