I've been working on a plugin for a LCD display and had the device working quite well except there was no config dialog. I ended up crashing mach3 so I installed the most recent non-release beta version. Now I have a problem in that the display is not picking up the mach3 machine data structure correctly. Has there been a change in the structure between the release and the current beta version?  Also, I've been able to create a problem with mach3 in that I am able to trigger a 9991 art code consistantly. Closing the dialog, causes mach3 to crash. this is extremely repeatable. I'm not modifiying the structures at all, just set up a dialog box and obviuosly incorrectly.

Probably best to email Andrew and give him details of exactly what happens and likely also your plugin etc so he can repeat the issue there.

Are you using VS2003?  If not, that could be your problem as some of the class sizes have changed and will cause memory corruption.

well that is maybe it then as I'm trying to use vs2010. I knew i should not have upgraded from 2003.

If you look in the plugin forum, there is a guy there that did a great job and doewrote some new headers so you can use VS2008, but it does not support MFC.

Thanks for the heads up Eric. Once I recompiled using the headers from the MachPluginWizard 1.1a I can say that  it actually works with VS2010. my LCD DRo is now working again.
