I haven't seen this problem, but I am on Advanced. Do you have any plugins installed? Current version of Java, or the version that installs with FMP? Have you tried uninstalling FMP, delete any remains, and perform a fresh install? Can you replicate the issue on another Mac?
I have experienced the same issue on fmpro14.4 (and fms14 as host). OS is Yosimite. Have replicated the problem on another Mac with same specs? I have to reboot FMP
