normally once you placed your windows (HP bars, chat, shortcuts, etc etc etc..), their position are save after you log off =o
i think the file which contains the information is planeshift.cfg which is located:
Linux: ~/.PlaneShift
MacOS X: ~/Library/Application Support/PlaneShift
Imac: /Users/<username>/Application Support/PlaneShift
Vista: C:\Users\User_Name\AppData\PlaneShift
Windows XP: C:\Documents and Settings\User_name\Application Data\PlaneShift
for windows (only?), it is a hidden folder. so you will have to make all folders visible
confirm your OS within your next post ;o)
