Graphical format in RTF export preferences is not correctly recorded

JSesh 5.7 (probably from a version or two) doesn't record correctly the graphical format (WMF, EMF, MacPict) chosen for RTF export preferences.

So, when starting JSesh, the previous choice is not remembered. The bug has been identified and will be fixed in the next version
(mea culpa, it is due to the use of copy/paste from the line which read another preference).

Temporary Workaround

get JSesh 5.8.
