if you ever pass in the result of XTPImageManager() to a SetImageManager function, things will blow up.
 
This is because things like report controls will insist on trying to delete whatever pointer it was given.
 
There are a couple of ways around this, but the most simple one would be:
 
override InternalRelease for CXTPImageManager, check an internal variable (m_bDeleteOnClose), and if it's false, don't delete it.
 
Add a constructor for CXTPImageManager so that you can construct a static one and set the variable to false.
 
Then it's safe to call InternalRelease on the image manager returned from XTPImageManager(), and therefore you can use this in your controls without having to copy and maintain synch with the global one all the time.

Hi,
 
Just call XTPImageManager()->InternalAddRef() after such operations.
