In the Object Palette, after changing schema and scrolling down to click on a table or view, the scroll bar spins back to the top and registers the click on the wrong table. The same behaviour occurs when scrolling down the column list of the selected table or view and clicking on a column.
In both cases, it occurs only on the first click after changing an item (schema or table/view). After this, scrolling and clicking is ok. It's behaving normally in previous versions.
