I have attempted to install the beta on an android phone that had never before had J installed on it. Then I tried using it and was stymied. I can't load or save anything. For example, I have an ijs file I want to use from downloads. Soon as I do the load and then hit ".." To walk the tree J fails.
Trying to make a new file, pick default name of 1.ijs and I get "no such file or directory" when I try to save...but the modified flag is cleared so it won't save again until I change the file. I believe that the j64-805-user and possibly ancestors were not created as part of the beta install. I thought about installing 805 and then 807 again to test this but could not find a link to the stable install download area on the J software site. This is using chrome on Android.
