Well, I found Mapper--it is still in the main program directory, just not launchable from within HRD now.
Unfortunately, it doesn't seem to read the locator information from the new version 5 Log program's database, so I can't plot my contacts on the map! The only workaround I have found is to retain a directory with HRD version4 in it, and maintain a copy of my log in the old (version 4) format for Mapper to read from. But that means I have to import any new contacts into the V4 folder every time I make a new contact.
They seem to want you to give up on Mapper in Version 5 and use the nifty Google Earth plotting provision---which is awesome, but I really like the way Mapper looked and printed with all the little stick pins in it, LOL.
Annoying!!! Plus I've had to spend the last 36 hours trying to figure out all the new stuff with V5. All this because QRZ made a small change in URL format? WTF??!! I would have been quite happy just to stick with V4 and have them fix the QRZ quirk.
