I will answer my own question: here is my config; which you have to manually edit in the keyclone.ini file as the custom rez UI doesn't exist (or seem to keep what you type in the drop down):



[regions]
count=3
region_name_00='main'
region_00=1,0,0,1125,900,0,0
region_pip_00=0,(122.0.0)
region_res_00=1125,900,1
region_name_01='wow2'
region_01=1,1125,0,1440,315,0,0
region_pip_01=0,(123.0.0)
region_res_01=630,630,0
region_name_02='wow3'
region_02=1,1125,315,1440,630,0,0
region_pip_02=0,(0.0.0)
region_res_02=630,630,1


the trick here is that if you set wow custom rez to 315x315 it is too small and gets reset to 800x600 but 800x600 doesn't scale well on a 315x315 square; so I double that value to 630x630 and that works fine

maybe an improvements on the maximizer config UI would be to have "1:2" instead of just "1:1" (and maybe some other ratios (or maybe it is really "2:1" ie wow gets 2x the pixels than real screen space)



Thanks for a cool tool !
