I have tested and can reproduce the problem. O4 works fine, and O42 does not. So this is a definite regression.

It will take some time to determine the root cause and post a correction. I'm a bit backed up at the moment.

Meanwhile, there is a workaround which worked for me. Simply edit the config file and change the ChartDir path(s) in there into a full, absolute path. Start O, Rebuild the database, and restart O. For me, this allows GL to work as normal.

Of course, in your world, it may not be so simple. You may need relative paths to accommodate relocated disk images. If so, this workaround might not help you as much.

Despite the workaround, this is a real bug. So please, if you have time, capture this in Flyspray so that it won't be lost. We do need to figure out the OpenGL dependency as the root cause.

Thanks, and let me know how you get on with the workaround.
