Hello all together again,

ich have another question on LON-CAPA 2.11.0 regarding the formula 
editor the user gets when clicking on the small pencil-icon right to the 
answer-box where a formula is required as correct answer:

I got a request, the editor does not start correctly. I verified that by 
klicking the icon described above and got a "blocked by security 
settings"-Error in Java (using actual Firefox on patched Windows, actual 
Java RE). The error ist described on 
https://www.java.com/en/download/help/java_blocked.xml and the third 
characteristic occurs ("Missing required Permissions manifest attribute 
in main jar"). The described workarounds (see my link) are functional 
but not the favored solution as not all users realize what they are doing.

As the cause of the error for me seems to be the missing "permissions" 
attribute in MainApplet.java which I associate is part of and maintained 
by LON-CAPA (is it?), I hereby communicate the problem hoping for a 
solution in a coming relase - is this possible? If you need more 
information on that issue, just send me an email :)!

Greetins from germany
