As for these tutorials, at least the poor guy has made an effort, there are some webcasts from MS too (at http://www.microsoft.com/events/series/msdnvisualcsharp.aspx?tab=webcasts ) and they probably might be very good but I could never get to them, it takes me into circles of registration and registration and more registration, don’t know what sort of usability study experts MS hires.

But I don’t agree with the rest, I think (I didn’t dig deeper into it that’s why I only *think* so) that stage.stageHeight returns the height of the *viewable* area (i.e. the height and width at which the movie is being displayed).

I say so because in the module mentioned above, I was trying to make my Sprite scale (and thereby incorporate more content into it) upon resizing the browser window. Using stage.stageHeight and stage.stageWidth worked for rescaling (i.e. calculating the size of viewable area and resizing the sprite accordingly).

I may be wrong, let me know if it is so.

stage.stageHeight returns the height of the actual stage (i.e. the area you see when running your movie), whereas stage.height returns the height of the CONTENT on the stage.
Say, you’ve set the dimensions of the stage to 500×500 and added a movieclip with the dimensions 100×100 anywhere on the stage, you would get the following:

trace(stage.height); // Outputs “100″
trace(stage.stageHeight); // Outputs “500″

If you have several movieclips, buttons, etc. on your stage, stage.height gives you the total height of all content on stage.

Hope this makes sense.

Anyway, start Ubuntu/Kubuntu in recovery mode, it’ll give you instructions to load the drive (and/or to delete the log entries) like mentioned above. Following those instructions should fix.
