I've post it in the house of healing but it may help those few who use 3.5 ruleset and not the jpg !

The bug is connected to combattrackeractive.lua

Change :
function onClickRelease(button, x, y)
if not state then
window.windowlist.requestActivation(window);
end
end

function onClickRelease(button, x, y)
if not state then
window.getTracker().requestActivation(window);
end
end
