OS: Ubuntu 15.04 (my repository update: 17 January 2016) 1. Open Math Formula. 2. Click Symbol Button. 3. Choose Symbol Set (example: iGreek or Special) I can only use the direction buttons to navigate between options. (mouse does not work)
Already fixed. As a workaround you can export SAL_USE_VCLPLUGIN=gtk. *** This bug has been marked as a duplicate of bug 96604 ***
