RunAdd BreakpointModule Load 

Adds a module load breakpoint that will halt program execution when the module is loaded. You also use this dialog when you click Edit Type the module name (usually a DLL or package) into the edit box, or click the Browse button to navigate to the module. 

This dialog box also adds the module to the Modules window. Modules are automatically added to the Modules window when they are loaded into memory, but if you want to halt execution for debugging when the module first loads into memory, you must add it to the modules window.
