Palettes disappear after shutting and opening new documents

Every time I open or shut a document, my palettes disappear. Then i have to open and reposition them over and over. This is maddening! I used to work in Adobe CS5 for the longest time and that never gave me an issue. Now that I've updated everything, InDesign is sooo slow, and shuts down all my palettes. I hate this.
Would like to see an Indesign update that fixes the palette issue and the slowness of InDesign. Also I would like to see a mobile version of Indesign so i can work on the go.
