I create a new text document and insert the follows text 'supercallifragilisti '
into the document. I realized, the red line under the word. The Autospellcheck
is online.
Then I choose Tools->Macros->Record Macro, click onto the Autospellcheck button,
store the created function. 
A simple test, activate Autospellcheck button again, Choose Tools->Macro->Run
Macro, choose my stored macro, voila autospellcheck is offline.
Now activate Autospellcheck button again, choose Tools->Macro->Organize
Macros->StarOffice Basic, choose the stored macro click on 'edit' and choose
'Run BASIC' out of the edit window.  Go back to the writer window, nothing has
happend, the autospellcheck is always online. 
There seems to be something wrong, because the same last behaviour occurs, if I
use a java program. Which tries to trigger the Autospellcheck button over the
java uno bridge.
