At the moment (BYOND 495.1136) the splash screen only requires a mouse-down to close/minimize. This would typically be non-problematic, however most of the time, the splash screen in relation to the pager falls in this order:

Since the BYOND logo seems to only require a mouse-up, and the red X falls in front of the logo, whenever I click the red X or the blue minimize button, it launches BYOND's homepage.
It's simple to avoid on the users end, but I think it would be an improvement to require a mouse-up to close the splash screen in general.

I don't see this as a very pressing issue.
