Optical flares BUG? - Need help

Today I met with a very unusual phenomenon, we work on a new project, using cc particle world in which the option is selected instead of the standard particles is set to custom texture of clouds and when I add optical flares (which should represent the sun) it is impossible to set the optical flares behind the clouds (custom texture), so when the clouds go to from time to time see the sun, I tried to add optical flares on SOLID or LIGHT (track light option ON) optical flares always stays in front of the cloud. Does anyone have experience with this? How do I solve this?

Miseld,

If your OF is set to track the lights if should work, weird is not working. Can you send me an email so I can take a look at your project?
