Maybe bad install? I'm a Strong proponent of
"If it seems broken
Re-Install because it is Linux"

I have this in my .bash_aliases
Alias Code:
alias mem='free -mt; grep MemTotal /proc/meminfo;vmstat;ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%mem | head; ps -eo pid,comm,%cpu | sort -rk 3 | head' #Top Ten

No Caja in my top ten...
when you break Linux you can fix it real easy.
re-install then play with it again!
you can look up installing Linux with "Something else"
you will find a few How to's
I set mine up like this (Close to this
this is a good place to START)
Hard Drive Partitions
512mb Primary - Ext4 Filesystem - /Boot
30720mb (30Gig) Primary - Ext4 Filesystem - /
8192mb (8Gig) Primary - Swap area (Make Swap same as amount of RAM if 8 or less only 2or3 Gig for more Ram)
Primary -Ext4 - /home
/swap not required by newer Boxes from what I understand
With it set up like this you can re-format Everything except your /home Directory and have a Band New OS without Loosing any important data.
You can re-install what MATE doesn't or can't and you have a Brand New System without sweating a Drop.

Good Luck and have Fun!
