SYMPTOMS
When you use ten or more breakpoints to debug an application that is built by using Microsoft Visual C++, the application and the debugger may start more slowly than expected in Microsoft Visual Studio 2005. Additionally, messages that indicate that a module has been loaded in the application are slow to appear.



CAUSE
This problem occurs because the application has many unresolved breakpoints in many modules. Breakpoints are unresolved when you set breakpoints in dynamic-link library (DLL) files.
