color:#1F497D'>It is likely (incorrectly) treating the remaining rings of the
polygon as holes and the intersection check fails for them. This instersection check
is done by the FDO provider, so it would be the SHP FDO provider that is doing intersection
wrong. One thing you could try – convert your SHP to SDF and see if it
still fails. SDF uses the same code for intersection, but may be the geometry
will be converted to the right kind of multi-polygon during the conversion
step. I know… this sounds more like a cooking recipe than a fix, but it
may help.<o:p></o:p></span></p>

<p class=MsoNormal>I've noticed this as well, and it appears to be just the way
the mapframe reads your x,y location. So the further zoomed out your scale is,
the harder to precision grab the x,y.<o:p></o:p></p>

<p class=MsoNormal>Now for the fun stuff. I create shapefiles out of ArcView
3.2 that are multi-part polygons. (So two or more seperate polygons for
one feature), and it would appear, that you can't select, or Task-panel click
on the multi-part polygons other than the first one in the feature, to get a
selection. <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>For example, a multi-part polygon with a 0.25 Acre triangle
corner polygon on the other side of a road, and a 100 Acre square polygon,
if the the 0.25 acre sized polygon has it's vertices index first, you can only
hit that small polygon in order to pull the attributes of the feature. Clicking
on the Larger 100 Acres polygon doesn't create a hit. <o:p></o:p></p>
