I made a spinning cube according to the example in GLSceneGuide_v1.9.pdf,
compiled it on laptop(lazarus 2.0.10 FPC 3.2.0) - working fine,
zipped the code together with the compiled exe,
copied it the the desktop,
ran the exe on desktop - working fine,
compiled the code once again in lazarus on desktop(lazarus 2.0.12 FPC 3.2.0),
ran it - flashing window where I could see the cube rotating.
Something is different, but what?
Have you solved this problem? I have encountered the same behavior.
