Hello.

I am running turn for quite some time. During a cycle, were I used frequently start and stop buttons for checking accuracy of the part being made, I lost the toolpath window (stop seeing the toolpath). I have stoped the machine, exited mach and load it again. Result: white screen (like no screen was selected) and no information about the configuration - the xml file was totally reseted. I add to load an old xml, from the backup directory.

Any ideas of what could happen? This is a new bug?

Thank you

Never seen or heard of that before, will keep an eye out for it. Was there anything you can think of that you did differently that may have triggered it?

I have try to reproduce the error without success. I was showing a machine to a customer  and constantly using feedrate pause, then cycle start while the piece was being made. After that I have try again to do the same and it worked fine. I have notice that the feedrate button stoped working when I lost the toolpath window display, maybe it is related, but I could not reproduce it.

Thank Hood

That is always when these kind of things happen, when you are showing to others LOL
 Will mention this to Brian but unless it can be repeated there is no way to even verify if its a bug with Mach or just a glitch in your computer, so very little chance of being able to find it if it is a bug.
