I cannot generate new frags. I am running SWP 6.0.11 with the Java 8 Update 73 on OSX El Capitan 10.11.3. When dragging a mathematical expression to the frags box, I receive the following Java error.

[Javascript application]

Component returned failure code: 0x80520015 (NS_ERROR_FILE_ACCESS_DENIED) [nsIFileOutputStream.init]
