Description:

a bubbleHelp view.

Instances of myself show up either as a comics-like talking
view, or as a simple square popup. This is configured via the
styleSheet; the default is simple-square. 
To get the fancy comics style, add a resource 'activeHelpStyle' with 
a symbol-value of #cartoon.
However, be aware that some servers have performance problems with
these view-shapes (or do not support shapes at all).
Therefore, the default style is a rectangular popupView.
