I'm no expert by any means so I might have caused this but I'll have to be shown how, if so.

I had an A size sheet layout that was properly aligned on the page in paperspace, it prints properly, etc. All was good except it was using the default printstyle and I'm printing to a B&W laser printer. So I changed the printstyle to monochrome: Print Configuration Manager, Additional Options button and chose monochrome.ctb in the PrintStyle Table section. I clicked OK and then the Print Preview button and suddenly the page moved to -X,-Y by about an inch or so. The CCS icon was still at 0,0, but the paper had moved. I changed it back to default.ctb but no luck. I stopped and restarted DraftSight but no change. After playing with it a bit but making no permanent changes in the Print Configuration Manager, I changed it from landscape to portrait and immediately back (without saving the setting). Next I clicked Print Preview and the page was back in the correct spot. However, my viewport had moved a slight bit. I've since deleted and recreated my (single) viewpoint and it's OK, but it doesn't seem to me that simply changing to monochrome should have caused the paper to move. Nothing else was changed.

Did I inadvertently do something to cause that, or is this a bug? This was all with the same print configuration, by the way.

Thanks.
