Saving your work
Sometimes you will think you've saved a page but find that you haven't.
The chief cause of this problem is often the size of the images on the page. As cameras get better, so the images we gather get larger and it can take 20-30 seconds to save a page.
Next time you are saving a page after adding an image take a look at the bottom of the page and watch the blue progress bar, the bigger the image the slower the progress.
Let it finish, it will only be slow the first time you save the image.
If you move on before it has completed saving you may be asked to wait, or you may lose the information...
