Has anyone had issues with setting a components line font with in a drawing?  We have a drawing that shows a modification to an aircraft console structure and we had all the views set up so that the parts being removed in the mod process are shown in phantom line work. Everything was fine as of yesterday but now when we open the drawing up, all the lines that where phantom are now regular line work and when selecting a component and looking at the component line font, its deverted back to default.  We have tried reselecting the components and changing to phantom but it does not take.... If you reselect the component again and select the component line format, it is set back to default.

I did copy a view from the drawing with the issue and pasted it into a new drawing and was able to change component line font with no issues.  What drives me crazy is that we were ready to drop this drawing into the release cycle and this happened while one of my guys went to open it and pick up a couple minor comments that came out of checking and now its all FUBAR.

At this point Ive directed him to save it out to ACAD and just change the line work there and be done with it because we dont have hours to spend trouble shooting a sudden hiccup with in Solidworks. This drawing has been in work on and off for about a month now with no issues and then suddenly there is an issue. I would post the file but with the restriction of this project I can not share the drawing.

We have opened this drawing on multiple stations with the same result. We are running SW 2010 sp 3.1 XP 64 as well as WIN 7 64  with all supported hardware and drivers.

Thanks in advance for any inputs on this.
