Thank you, that was the problem. Were looking at Mastercam X, but the time to learn the new interface from v9.1 to X6 has been the problem as v9.1 dose everything we need.If it were me, we would have switched over long ago.

I its been a while since I've used the thread milling program in mastercam v9.1 and I have a problem. For what ever reason, the major thread diameter box is grayed out, I remember this happening before, but I can't remember what I did to fix it. Thanks for any help.

Rob, Turning off hardware acc worked, and I have my arrows back, but really showed down Firefox, it scrolls in big chunks. I didn't mess with OpenGL, so it running. I do have a simple optical Logiteah mouse. Were going to look into a Quordro 2000 vid card.

Yes, the IT guy here at work logged on to make the change, do you have to turn it all the down? After you did this, was the mouse and scrolling very jerky? Scrolling was happening in chucks after turning it down.

Tried it, it didn't bring them back.

We tried turning hardware acceleration because of driver problems, but the mouse and scrolling became very jerky, I didn't notice my arrows came back, but will try it again. How do I turn off openGL?

Thanks for the reply gcode. I don't see anything in WinXP for best performance, but do you agree that the missing arrows are related to the card? If I hit revers I get two arrows, but it doesn't matter which one you click on, it reverses the chain.

The most recent drivers say that its using OpenGL version 6.14.10.11796 in the Catalyst control center, which we just installed. But the chaining arrows still aren't working. I didn't disable OpenGL in the system as recommended, does this still need to be done?

Thanks for the reply Bigjohn. Are you referring to the the text that comes with the post? If its the post file, how would I open it to view the first line? To be honest, I don't know much about posts, but I really need to get this post working.

What are the issues with the ATI v5800 and Open GL?

The OS is WinXP video card is a ATI v5800, and we have had problems with the drivers.

When I used to chain a contour there were little arrows that showed the direction of the chain, after the reload, there not there anymore. How can I get them back? Also, mastercam used to make sounds, now its silent, how can I get that back? When I go "file-get" the right side of the box is missing, it has something to do with running the fonts at 125% so the graphics are larger, has anyone ran into that problem?

Its been so long since I've used this post, that I don't know what version it is. How do I find that info?

Just tried to update, still getting errors.

We have a Hermle UWF 1200, it has a X and Y axis spindel. I haven't used the Y axis in a long time, and the post I was using doesn't work with Mastercam v9.1 even though v9.1 is old, the post is much older. The problem seems to be with circle center. Does anyone know where I can find a post that will work? BTW The Z post we use doesn't have any issues at all
