The splash screen was changed so that it doesn't stay on top of other windows.
Making the splash screen stay on top on all other application can be very annoying when working with other applications, because it cannot be moved out of the way.
We made this fix after reading the error reports. Thank you for reporting, and don't hesitate to tell us about other problems as well. Other issues might take more time time to fix, but we always keep track of them. You can also discuss on the forum about such problems.
This fix is will be available from the next release and in all nighty builds. Thank you for the cooperation and enjoy NaroCAD.
