DLL not being released

[Sammy_S]

I'm having a strange problem within VB6, here's a simple example where an app calls a DLL which prompts a message box and nothing else. Why does the DLL remain in memory after completing the call to the DLL. I know it is still in memory because i cannot recompile the DLL while the calling app is still running. What's going on!

DLL:

Public Function Test()
MsgBox "Test"
End Function

My App calling the DLL:

Dim obj As Object
 
Set obj = CreateObject("Test.Class1")
Call obj.test
Set obj = Nothing
