the remainder of the old ole controls filter msocximex.[ch]xx is 
effectively removed [1] and all the remaining functionality ( mosty 
export support for OLE controls ) has been removed. This is a large 
change so please beware and report problems in this area. I have done 
some testing with import/export ( for calc and writer but NOT powerpoint 
). Ideally there should be no ( negative ) difference between 
import/export of OLE controls between master and 3.4. However there are 
some known issues

a) there are at least some problems with reading the result of exported 
MorphDataControl(s) where a MorphDataControl is one of the six controls: 
CheckBox, ComboBox, ListBox, OptionButton, TextBox and ToggleButton ( 
these all share the same export routine ) The remaining controls types 
CommandButtons, ScrollBars and SpinButtons seem to export ( and be 
readable from Microsoft office )

I of course will fix the export of the above controls but as the patch 
is so big I really need to commit it as it is getting hard to maintain.

thanks,
Noel

[1] there is just now a small piece of code remaining in msocximex, to 
remove it looks like some changes would be required to the powerpoint 
filter and some code that is present in the filter module would need to 
move out to sd.
