I have a number of toolbars with custom scripts, including one for STL exports with predefined settings. I am building a test part and I went to export it as an .STL with one of my predefined settings. I first preselected the part and then hit the flyout toolbar and picked one of my preset buttons…

@Helvetosaur this is a known bug and happens only with the new Eto command UI. It’s on @curtisw list What you can do for now is switch to the legacy commandline (TestEtoCommandUI)

OK, since my command line didn’t look any different, I didn’t realize that was activated - I guess it is now by default. Setting it back to legacy does indeed fix the issue for now, thanks.
