I have made some fixes and posted a new version, now 2.76
The tool selection screen has been fixed to properly handle metric tools. I has apparently been wrong since the beginning, I guess not a lot of guys use metric tools ;-) Odd bug, it was supposed to test LED 1020 to see if it was metric, but it was looking instead at DRO1020, which happened to be a value on another screen.
I also fixed the tool table dialog box to display the tool description field. Art added a VB call for that some time ago, I just got around to fixing it.
I also made major changes to the thread milling screen. I believe it is now safe from all tool crashes, but check your code before you crash an expensive tool!
The one remaining problem I am aware of is that the circle wizard does a radius in move when you ask for a groove. That screen has some very ugly VB code and Im not quite ready to hack it apart yet. I will get there.
