LO Base - Check boxes not working after upgrade??

FIRST POST DID NOT SEEM TO GET THROUGH - RE-SENDING .......

Hi All

I use here PClinuxOS 2013 (up-to-date), My SQL 5.1.55 and have just upgraded my LO Office to 4.1.2.

Everything seems to be fine
EXCEPT
The Check Boxes in my LO Form no longer work - you can not edit them or add to them. If you click on one a tick appears in the box but as you select Save the tick disappears and it is *NOT* saved.

I have even tried and created a new Tick Box and it behaves just as above,

Has anyone seen this effect or got any idea how to fix it please??

Thanks or any help.
