Many of Mediagraph's features refresh and update automatically as you work. Sometimes, your deisred change may have been made in the background, even though the display in front of you may not have updated accordingly. For these cases, there are Refresh buttons throughout the app. If something in Mediagraph doesn't look right, the first step is to click the Refresh button for the feature you're working with. Often, you'll find that clicking Refresh will clean things up immediately.
