[Inkscape-user] Docking

Hi all

Using Gimp 2 on Windows XP, I "undocked" the tool options palette by mistake - how can I re-dock this? Note that on my (XP) display, there is no double line at the supposed docking position at the foot of the box (if you follow me!).

I would send a screen shot but I think attachments are stripped by the list server?
