I have just installed 4.03 3D after previously using 3.11 2D - all seems to work fine but after a while I lose the ability to click anything with the mouse pointer and just get that annoying windows 'ding' noise (using windows vista on my laptop). My only recourse is to launch task manager and close the program from there, anyone else experienced this and know why it's happening?
This is caused by the Preferences window 'dropping' behind the main RB interface window.
Use ALT+F4 to close the 'hidden' window and then try using the File>Preference>3D Settings instead of the 3D Settings button on the toolbar.
This does happen to me too occasionally. If it keeps happening and you want to see it, use ALT+F4 to close the window, then make the RB window smaller so that it only covers half the screen, then hit the 3D Settings button again - you will see the Preferences window sticking out from under the RB window.
AirNav are aware of this, but as it only happens occasionally to a few people, I think that its been difficult to find the problem.
