Open
This menu item shows a file open dialog.
If any images have been loaded before HotEdit changes to the directory
of the last opened image.
You can only open GIF and JPG files because HotEdit checks
the physical fileformat of the file opened.
If the file have the correct graphics fileformat HotEdit
checks for a properties file containing additional information.
This properties file only exist if the image have been opened and
saved before.
If the image has the name (filename).(extension) the properties
filename is (filename).DBHotSpotGroup.
If the properties file exists it will be loaded. If successfully
loaded the image will be shown on the Frame Windows client area
and updated with information from the properties file.
