AppCrash when Secure Lockdown enabled

Hi

Anyone experiencing regular appcrashes when enabling secure lockdown?
I have this issue with many computers i have lockdown enabled on and cannot work out why

The program is a CCTV based program which allows allows viewing of live camera footage from multiple cameras
The footage is delivered to the PC via multiple multicast streams
Could Secure Lockdown be blocking a specific port?

Inteset staff
Do you have a list of items such as ports blocked? or anything relating to multicast?

Thanks

No ports are blocked by Secure Lockdown. If the System Lockdown > Local Level > No Desktop option is enabled, try disabling it.
