Excellent! Now, in the light of this new finding, we have to reasses the listview situation. Did you get a chance to rerun Drew's tests for the listview?
No, not yet. I'm not convinced they are the same bug, Drews test cases indicated the documented behaviour on Windows, whereas Mikes test case showed incorrect behaviour for the listview on Windows.
On the other hand, you were right last time, so when I get some more spare time I'll install mingw on my terminal server account and modify the test case to use a listview instead and see what happens.
