#776 Graph Panel half black

[Nicole Sigaud]

I can't see the graph, since half of it is always in black. I use a Windows 7 Home Premium SP1 64-bit laptop, 64 MB video memory (dedicated), total graphic memory = 1696 MB, Intel HD Graphics 3000. Processor = Intel Core i5-2410M CPU 2.3 GHz, 4 GB memory.

I tried for several times to open a graph, but it just does not work.

Also, it made my system crash (the blue screen) while trying to select a node

OK, I managed to solve the bug - updated the OpenGL driver. This deficiency in a computed could be detected while opening the software, because it's not a bug, just a sort of incompatibility with an outdated driver.

Thank you very much for your input.
The Tulip 3 code which was used to check the current opengl driver
capabilities, has not yet been reintegrated in Tulip 4.
