I've written a C++ driver that renders a Flash file into a DirectX texture,
after which it can be either shown in a sprite or be used to map on objects.
The sprite version is also interactive and processes input events. Most flash
files work but those created with Flex run into problems. Some files will get
stuck at the end of the initialization phase. No ActionScripts are called (such
as init or creationcomplete) and the CPU will be spike to 100%. I haven't been
able to find any patterns that might explain this behavior.

Has anyone seen anything like this and if so does anyone have any solutions to
this?
