Here's a quick run through of the activities.

Correctly positioned:

	Memorize
	IRC
	InfoSlicer
	Write
	Chat
	Terminal
	Browse
	Joke Machine
	Poll Builder
	Paint
	Labyrinth
	View Slides
	Image Viewer
	Jukebox
	Read

Offset, incorrectly sized and/or other related issue:

	Jigsaw Puzzle
	Moon
	Calculate
	Pippy
	TurtleArt (locked up, very slow, unusable)
	Record (main window OK but preview window ends up obscuring much of  
the UI)
	Etoys (mainly black screen, very slow, unusable, would not fully stop)
	FreeCell (mainly black screen, very slow, unusable, would not fully  
stop)
	Story Builder
	TamTamSynthLab
	TamTamMini
	TamTamEdit
	Slider Puzzle
	Cartoon Builder
	Flipsticks
	Develop
	Log

Watching the re-draw as things (messily) start-up, it kind'a looks  
like windows are initially opened at a mix of different sizes (some  
too small, some too large). The activity then sets-up its UI, and only  
then receive some late window manager event to go fullscreen.  
Activities that don't expect their window to be dynamically resized  
stay offset and/or incorrectly sized.

Here's a few more:

- When activities are started you initially see a sugar-session window  
with traditional widget decoration (close/minimise/etc) and title,  
again after a few seconds delay the pulsing activity icon begins and  
then the window decorations switch off and the window re-adjusts its  
size/layout.

- All activities end up with a 3-4 pixel grey boarder around their  
outer edge (Fitts's law issue as right/bottom scroll bars are no  
longer at the edge of the screen).

- You can still drag a fullscreen activity window around using the top  
grey boarder.

- Holding alt down and dragging, drags a fullscreen window around from  
anywhere.

- A few times when clicking the grey boarders I managed to trigger the  
window manager's context palette and window resizing cursors.

- Watch out for some window manager shortcut keys Alt+F9, Alt+F7, Alt 
+F8, Alt+F4.
