Order of instrumetns' within the workspace

After the last update it is really difficult to slide the instruments windows in order to reorder them. In essence, I want to have all the instruments in a certain order when I open my platform, so that commodities, currencies and indexes dont get mixed up. Occasionally one of the charts gets mistakenly extracted, and ends up at the bottom of the pile. To slide it back to its position is now an absolute nightmare. Is there a way to establish an order for all your instruments in your workspace?
