The "leading zero for values less than one" box is unchecked in "settings/dimensions" but I'm still getting them. I have it set that way in the part template. It stays unchecked in "options" each time I start a new part but I'm still getting leading zeros. I've had some crashes lately and some of the defaults changed and had to be reset. "Broken leader line text position" wouldn't stay set for awhile but seems to be stable now. Any ideas short of doing a re-installation?
You didn't say if your dimensions are set to display as decimal or fraction. I suspect that they're set to decimal. Even with the box de-selected for "Include leading zero for values less than 1", if "Zeros > Leading zeroes:" is set to "Show" they'll be displayed for decimal values.
