In the Basic IDE, if you place:

Option Compatible
Option ClassModule

At the header of a Basic Module, double clicking method names on this module will stop working in the Object Catalog.

For instance, consider these macros in Module1:

Sub Macro1
	'Dummy Macro
	MsgBox "Dummy 1"
End Sub

Sub Macro2
	'Dummy Macro
	MsgBox "Dummy 2"
End Sub

Sub Macro3
	'Dummy Macro
	MsgBox "Dummy 3"
End Sub

Sub Macro4
	'Dummy Macro
	MsgBox "Dummy 4"
End Sub

If you create them in Module1, it is possible to navigate the macros using the Object Catalog and double-clicking their names will move the cursor to the beginning of the macro definition.

However, after adding "Option ClassModule" at the top of the module and compiling the module, double-clicking will stop working.
