<p dir="ltr">Thanks for those ideas. I can check off most of those items except upgrading. This is new development so likely computer based? Rather than QGIS. </p>

I have done this in the past without errors in QGIS. I would upgrade to the latest version. Then to figure out where the problem is, I would:</p>
<p dir="ltr">Make sure that both layer are polygon layers (and not lines and polygons), that both have the same CRS (along with the project CRS), that both have the same fields and that the "receiving layer" is in editing mode, and saved subsequently. I would limited the amount of open files and open plugins.</p>
<p dir="ltr">Try copying polygons from a newly created file to an empty newly created layer in QGIS and not a shapefile that was previously manipulated in other softwares. All this could help you find the source of the problem. </p>
<p dir="ltr">I would also look at the bug reports to see if it is an issue for that version. </p>
<p dir="ltr">Hope this helps.</p>

Hello Group,<br><br>
Am using
QGIS 2.10.1 and have done so without significant problems for many
months. I am attempting to create simple polygons in a shapefile by
direct vertex entry or copying polygons from another shapefile layer and
pasting them into the active layer.<br><br>
In almost
every case, these features disappear. There is an entity entry in
the attribute table but there are no polygons created. In one case
a polygon was created but it was not the shape that I digitized; no more
polygons could be created although the process for doing so appears to be
working. No error messages were created. The CRS for the
project and the shapefile are the same.<br><br>
The
shapefile can be opened in another GIS but has no content.<br>
<br>
Here are
some product details: QGIS version 2.10.1-Pisa QGIS

Thanks
very much for any help you can render, Cheers . . . . . . . . Springfield
