NEED HELP! particle operator buggy?

hi there, my problem: when i load footage e.g. a .tga, an avi etc. into combustion and then add the particle operator to it, it switches to that operator and the layer (the .tga) i am operating on turns into 8-bit mode and not anly that, the whole comp is now displayed in 8-bit and even rendered!!(not per channel, the layer is displayed with 256 colors) can someone tell me about, why this happens ?? when i delete the particleoperator, the comp got it's old color-profile back (32bit) would appreciate any help, thank you!

The Particles operator is only 8-bit per channel, but I don't think that that should be changing your entire comp. I've not worked with mixed bit depths in c2. (Read the "Working with Bit Depth" section of the docs.)

It could also be a problem with your OpenGL board and the Particles preview. Try it with Software OpenGL setting in prefs.
