RepRap host under windows XP

I have to say thanks to all who responded, and other threads that I just found today, whcih cleared up a lot of old outstanding problems I had with the host and firmware.

Just got one more.

Typical error message

Now i'm no Java programmer, and I cannot tell if this is a problem with cleanup from a normal exit, or even after a crash of the host, which ever it is, I have to do a full system restart each time.

I have the latest Java 6
Windows XP 32bit
Host from sourceforge, version 20100806

Does anyone know of a way to fix this?

Cheers

What the error says is that there was a crash in an external library that the java code was calling. The crash was in this library nvoglnt.dll. Which is nothing to do with the Host software. I suspect that you have triggered somehow a bug in java and its interaction with this library

Interesting, though I still believe it is a problem host side.
A search of the file says that it is the nVidia OpenGL interface driver, which I had up to date months ago, and pointless to update as there are no new changes for my video card, 8800GTS 512.
I have also played with recently a game called RoboForge, which runs under Java and OpenGL, and had no problems I could see.

Is there a way to be sure that it isn't some bad/missing code in the host that could cause this?

Edit: I will have another go with RoboForge tomorrow to see if I can replicate the problem there.

How to select a port for windows

/dev/ttyUSB0 - not working
/dev/ttyS3 - not working
/dev/com4 - not working
com4 - not working


P.S. reprap-host-windows-20090804...

Try COM4
