That page has not been changed for some time, but I will make a note to move the button up. Using the screen editor to fix it yourself is easy if its a big problem. I do my testing on a big screen, but do not maximize the window, I run it at 1024,768 which is the default window size.
The top topic in this forum is now sticky and contains the latest version.
Which pocket are you using? Is it possible you have some condition set that is making the code run a long time- like asking for 10" deep in .001" increments?
The only reason you could not return from the preview is if Mach is still processing the code, as it does before a preview. Maybe you have found an infinite loop, cut rectangle had one, that was the fix in V2.85
Can you post a screen shot of teh wizard with all the DRos filled in?
You are correct that the material DRO is the same as the X center. There was another duplicate that I had fixed. Im traveling now, I will correct this and release a new version when I get home next week. Sorry for the confusion and not checking your first report closer.
The wizards should always remember their last value used. These values are stored in the file Newfangled.set.def in The Addons\Newfangled folder. Check to see that this file is not set to read-only. If you copied the wizard from a CD it might have been set read-only
