Since Openbox 3.5 version its osd.button.* new options, I can't install a obt theme with LXappearance:
"Unable to extract the file "*.obt".
Please ensure that "~/.themes" is writable and that the file is a valid Openbox theme archive.
The following errors were reported:
tar: */openbox-3/(null) : not found in the archive"
I must do it through obconf.
