Ok so I installed 11.1.2.1 today nothing much has changed so far. (smoothest upgrade so far) Will update if I find any problems. All post from now will be for 11.1.2.1. Having a problem with multi edit list lovs - if it is a large LOV and you scroll down the LOV stays in the fetching data state - will try find a work around.
