Yeah, using the VPC position will not work. Travis is right - those
x/y coords change as the user prefs change for the current page/HTML
content.
You can build some custom functions based on the GetTag functions -
coupling that info with the GetElementDescription info, you should be
able to figure out which object you are referencing. Here is the
pseudo code I was thinking:
1. Use GetElementDescription to find the tag associated with the
current VPC item. Keep track of all attributes here.
2. Loop through these tags on the current page using either the GetTag
functions or the DOM.
3. Look for your attributes you gathered in step 1.
4. Once you find the matching attributes, save the object pointer.
