The problem I'm having is the following: is there an elegant way to

Savers panel in System Preferences?
The reason why I'm asking: when the user changes the configuration
in my screen saver, I start a Spotlight query that could take up to
30 seconds (about 10 seconds for the initial phase of the search
itself, plus 20 seconds for retrieveing the results from the query).
The results of that query then change what the screensaver renders.
Therefore, I would like to give the user some feedback that the
query is still in progress *AND* I would like to prevent the user
from clicking that 'Test' button in System Preferences' Screensaver
pane.
Right now I'm using an asynchronous NSMetadataQuery, which seems to
work, except that the only way to prevent the user from clicking
that 'Test' button I found was to keep the configuration sheet up
until the search has completely finished.
I don't know of a way to disable the "Test" button, but I wonder if
that's the right approach.
When the user changes the configuration of your screen saver (assuming
this is done by selecting the "Options" button and changing the
settings presented), what do you show in the Preview pane? Perhaps
displaying some static view with a progress indicator in your screen
saver view would be a better option?
