freezing loses FX?

It appears that freezing a track does not include the FX? 
EG the compression and VX64 both went gray and do not seem to be working on playback?
I am having dropouts during editing and playback and thought I'd freeze trax to help take a load off, but have not done this before.
Anything else to consider as a result of freezing?
Thanks

Thanks, 
These were not synth trax but the FX bin (side) compression was grayed out and did not work on play back.
Does it mean I can't continue to mix new trax and include frozen trax?
I hear them, but not the way they were set up.

if you're sidechaining compression, turn off the compressor then freeze the track, then right-click the fx bin and uncheck bypass bin and turn the compressor back on.   alternatively you could solo the audio track and the sidechain key and bounce to track.  since sidechaining requires two or more audio sources, freezing a single track won't yield the same results.  you could also throw the sidechain and fx on a bus then freeze the audio track that's running to the bus.

hth.

If you are running out of resources while mixing, try raising latency, archive unused tracks and freeze synths to free up resources.

In that case I think swamptooth's suggestion is the only solution.
