Saving Super Slow

I run into this every so often.  I go to save. The save dialogue comes up, and then i hangs. When it starts to save it says estimated time: 1min. and then 4-5 mintues later the progress percentage increases and so does the time, and then again, and again. The project size is 35mb and does not contain huge amounts of video files.  This is something that comes up repeatedly upgrades have not solved the issue. After I let if finish saving I close and reopen. If I know I have not done much, since my last save I sometimes force quite. It is getting really really problem matic. 

Only happens in AE that I have seen. Not Premiere or AI or PS
