When I installed Studio on my Linux system, it appears as if the connection wizard and properties editor tabs are out of order. When you click on "New Connection..." the first thing you see is Browser Options and all buttons are disabled. If you unselect "Get Base DN from root DSE" you can go then click the "next" button and configure the network parameters.
If you edit properties of an existing connection the editor tabs are in the same order.
I will attach screenshots to demonstrate. I also tried the same thing on Windows which appears to have normal behavior.
