2 issues:

In the insert image dialog box when you select an image you have to select it again to see it in the preview.  Once the image has been selected the first time, you can click on it again and it will display immediately.  Is there a way to make it display the image the first time the image is selected.

If you have a large folder structure of images or documents, the dialogs takes forever to load.  I believe this is because they are determining the amount of folder space that is being used by the images/documents.  As we don't care about folder sizes, is there a way to turn off this check so that it doesn't take forever to load and navigate the folders or are we stuck with a slow dialog?
