(the first is default since toolkits have used ~/.toolkitname stuff for a long long time). you have an interesting home directory i have to say... mr. corpuser # 10102229. :) so all that will not work here is that it wont pick up new config changes as you have no existing config for your user... until you do have it. elm's config loader literally mkpath'd that dir tho on startup (in _elm_config_sub_init()) so it should have been there even if empty ... have you somehow forbidden your elm apps from writing to there? making that dir path? there is just one place where we add a monitor for that dir were the dir isn't mkpath'd before .. but that should be long after the above init func so it should be created. i'll add another mkpath there... but maybe the issue is permissioning? > but the warning is a bit disconcerting.
