FMPA16 - Windows 7
Opening FM16's Layout Object Inspector (LOI) uses a LOT of memory each time you open it, and it doesn't seem to release that memory when closed.
On a very basic 6/7 object layout, opening the LOI adds about 4 mb of memory use. Closing LOI sometimes returns me 1-2 MB and sometimes nothing.
Opening a more typical layout (about 100 objects) adds about 25mb of memory use each time I open it, but upon LOI closing only releases from 0 to 3 mb. Switching layouts (in layout mode with LOI open) causes similar increases and only very small eventual decreases. I can EASILY run FMPA's memory past a gb just in the normal course of development use over a couple hours.
I happen to be using CTRL-ALT-T to open and close the LOI, though I don't think that makes a difference.
