I've got a Flex project file (let's call it main.iml) whose IML file defines a few Flex applications and contains several other modules. Most of those modules are for SWC libraries. However, one of them, let's call it other_app_module.iml, is for a semi-related application with its own SWF file. As such, it is listed in the modules.xml file but none of the applications in main.xml depends on it.
Whenever I open main.iml, I get the following popup:
(the obfuscated part is, of course, other_app_module.iml)
What's going on here, and how can I stop it?
