I am wondering if anyone knows of a bug with the 0.5.3 client that would cause the harddrive to continue filling up even when the client is not running.  
I am not talking about normal downloading of the blockchain either.  Something seems to be consistently taking more and more storage space.  I have deleted probably 50gb+ worth of content from my harddrive and it was filled up again within a day and a half.  It is also causing some pretty big problems with Audacity (as in losing entire hangouts).  This might be Audacity too...or even a virus, but I have to first ask about the bitshares client because that is the only program I use that can be expected to still be heavily buggy.  
Thanks for any information/advice.
