I have a shapefile, and it's got a self-intersecting geometry in it. I'd like to fix the self-intersection, but it will require a few moves. When I attempt to move a point using the QGIS edit tools, I am warned that the resulting geometry is invalid (I know this already) and that my last change has been reverted. What do I do here? Is there a way to suppress these warnings in QGIS so I can make the change, and only have it enforce validity when I'm done?

Which version of QGIS are you using?

QGIS 1.5 'Tethys' (1.5.0) has a fix for 'Allow editing of invalid geometry in node tool'

I'm on 1.4, but I'm grabbing the new one right now. Thanks for the hint! –  Michal Migurski Sep 4 '10 at 6:13
