I have been tempted by the recent posts on OpenGL to have another go. So, I tried the "animate.for" example and all the others in the opengl demo directory, and they work, but crash if the graphics windows are minimised. Typical error message follows:

In the debugger, it shows that the crash happens in "iglicd32.dll",

Any thoughts?

Works like doctors prescribed, minimized or maximized.

Ian,

No problems either!

Where do you have "iglicd32.dll" ?

I've never heard of it and its not on my system! I think your problem may not be FTN95 but something else in the set up of your OS.

Sorry I can't be of any real help.

cheers
John

Thanks Chaps,

Nothing is working here today. I'll have to try another machine.....pause...

You are right, works perfectly on the computer next to me. I'll have to investigate.

Regards

Ian

The dll is:

OpenGL(R) Driver for Intel(R) Graphics Accelerator version 6.14.10.4421

Probably a bad machine!

Ian,

Unfortunately OpenGL graphics aren't as rock solid stable as GDI graphics (using %gr). I see that DLL is part of the graphics acceleration, as I said in the other thread, if you disabled graphics acceleration does the problem persist? I don't know how %og initiates OpenGL, but talking to C++ programmers they inform that it is possible to interrogate a machine to find available graphics modes and select a non-accelerated mode for OpenGL, which I think would solve these problems. After all isn't acceleration intended primarily for games?

This computer is locked by the IT dept, and I can't turn off acceleration. I have to say, that the speed of rotation of the block in the animate.for example was far faster on my machine than the chap's machine I tried it on, so I assume the acceleration was doing something.

The machine detais are:

Thanks Dan,

I'm glad I don't own this computer, it is a heap of scrap!

Regards

I made the mistake of buying a compaq presario laptop some years ago, it will not run FTN95 OpenGL graphics at all ! I know the code is fine and runs perfectly okay on other machines. It doesn't handle GDI graphics too well either! The machine regularly shuts down when it gets too warm. It has a CD writer, which is useless, because before it can finish writing a CD it shuts down to protect the processor from frying itself.

It all works fine on my home machine which does not seem to have much in the way of acceleration anyway.
