I can't say what the issue is but when I use this to select a folder and then I want an inner tree to the folder I have selected I type it in at the bottom it tells me it does not exist and ask me if I want to create it, I say Yes of course and it always comes back with a failure. Sometimes it gives me a network path check etc...
I am pretty sure I've used this before for doing this...
I checked marked the option to create a prompt on creation and that works but it still fails to create it.
This is Win10, this is getting frustrating.
P.S.
I just tried with the OldStlyle Dialog and it works there...
guess I'll have to live with that, there is something wrong with the current style it does not work!
