Are the palettes not there, or are they just not in the group? I.e., after you restart ABS, if you dropped in a palette called 'XYZ', does it show up in the palette customize list... check by right clicking on the tool palette title bar, and select Customize... scroll through the list of palettes to see if your palettes are there.
I'd also suggest that you monitor what is happening in your tool palettes path as you drag and drop palettes in... i.e., the Tool Palettes File Locations in the Files tab of Options. Open that folder in Windows Explorer, then drag and drop a palette from the content browser to your tool palettes... does an .atc file starting w/ .the name of the palette show up in that folder?
