Hello, sorry for the late reply.
This is what the executable looks like for me. It does not respond to the TAB key. The screen also starts cut off to the left of the display, but I moved the window to take the screencap.
A text field is indeed visible when the executable first boots. This time I tried typing a longer string and could see the text after a few keystrokes -- as I said, though, the leftmost part of the window is cut off and attempting to move it will take the text box out of view. Also, I can't resize the window or switch to fullscreen (tried "F", "F4" and "F11"). Any commands I should try? It will probably accept them even if the input line is not visible.
