Hi,
during my testing I've found out that the configuration tool V3.x deletes(!) all Ir ccommands of the light buttons when you edit and customize them!
I'm using "LC2" in the config tool for my Lightmanager Pro as it behaves and imitates a LC2 perfectly.
For example:
I open "light" in the config tool edit view, copy the button "all off". Then I go back to the zone "livingroom" and place the button "all off" on the second page. Now I edit it via context menu (color: red, rename to "all lights off" or s.th. else).
Now when you go into view mode of the config tool to test your buttons there's no ir command associated to this light button. Everything gone!
I can reproduce it for every button of the light area.
