Actually, if you run your mouse over an item, move it or hit the alt key nearby the properties will be set.
For items placed directly into your inventory, you need to open your inventory and identify it to set the properties. In this case, move it before saving if you want to try re-loading for something better. I got a very nice ring in Verdistis from one of the healed soldiers, saved the game and re-loaded a few times. I decided I wasn't going to get anything better than the first, and re-loaded that save... only to find that the properties had not been saved. <img src="/ubbthreads/images/graemlins/cry.gif" alt="" />
