+1 for merging Chris' change to trunk.
While I have a hard time reproducing the useability scenario that
Chris describes, I can demonstrate the underlying problem as follows:
1) Enable the "Mouse over for keyboard focus" preference.
2) In a workspace, with a transcript window open start the following process
to log the keyboard focus to the transcript:
[[ (Delay forSeconds: 1) wait.
Transcript cr; show: ActiveHand keyboardFocus printString ] repeat ] fork.
3) In the same workspace, with that workspace highlighted for keyboard
focus, do this:
Smalltalk snapshot: true andQuit: true.
4) Restart the image, keeping the mouse pointer away from the new Squeak
5) Watch the transcript. Move the mouse pointer into the Squeak display
window, then back into into the workspace window.
Prior to loading Morphic-cmm.1618, the keyboardFocus is the remembered
value from the time of the image save, even though the mouse pointer
is now elsewhere. The correct behavior should be that the mouse pointer
is nil until it is actually moved over a text window, and this is what
I see after loading the fix.
Note that Marcel is away for another week or so doing PhD stuff, but
I am quite confident that he will agree with the above, so I suggest
merging the fix now so that we don't leave it on Marcel's overloaded
to-do list when he gets back :-)
