I uninstalled my 5.40 install, clearing all settings for all Windows users.
I then installed 5.40 RC3 clean install. I changed the "data folder" and the "download folder" to custom settings.
Later on, I decided I want the data folder on a different partition. Well, unlike the previous versions I have used, this one has a button to allow me to open the current data folder in Windows Explorer, but where would I change it? You can see that I can still change the download folder to wherever I want.
Normally the first two options would be to change the absolute path of "download" and "data" folders. This screenshot shows my situation; seems strange?
