Making a new partition in Macrium

[foxy]

TITLE SHOULD READ EASEUS, not Macrium. Can a mod please change it?

I belong to about 30 forums for software and I don't want to join another to get this answer about Easeus Partition Master, so here goes:

Bought a key a while back and I just did a new clean install of Win7 Ult on another machine. (I'm keeping 7 for the long haul.) I always partition it into 2 parts, C for sys+prog, D for data.

The help file for Easeus Partition Master says: "if you have unallocated space, use that to make a new part."
https://www.easeus.com/support/parti...partition.html
They don't say what to do if you want to make unallocated space, or at least I couldn't find it.

D must be after C, but the C drive refuses to resize. I've tried changing the size, but it goes back to where it was, and also sliding the arrow, but it won't slide. Since I use Easeus only once on each machine, I don't remember what I did last time.
