Beware the Sulfites. Sensitivity to sulfites is common among asthmatics. For me, an allergic reaction can result in a severe asthma attack. Dried fruits are usually responsible for the reactions. As with all processed or manufactured food items, I consistently check labels.
In some rare cases, dropped frames can be caused by an old network adapter driver doing a poor job of handing the high speeds being consumed. It's not a bad idea to just check to see if there are any new drivers for your network adapter, just to be sure.
The rest of this page is devoted to the disadvantages of frames. As you can see, it is my opinion that frames have more cons than pros. A broken frameset happens when the frames are not loaded or displayed correctly, for example, a menu frame is missing or one of the frames takes up the whole window.
