I haven't used halmeter before but I'll try and see if I can figure that out.
Here are my gui (vismachtesting.txt), postgui (vismachtesting.xml), hal (vismach-testing.hal.txt), postgui hal (vismachtesting_postgui.hal.txt), and ini (vismachtesting.ini) files; I am guessing you probably don't actually need to see all of these, but figured better too much than too little.
Maybe I need to loadusr the vismachtesting gui file in the postgui.hal file? But the bridgemill example postgui.hal doesn't use loadusr for anything, so probably not...
Thanks very much for your help
