I had two problems when working in a model today.

The first was this: I drew a line and a circle then deleted them because they were not needed.  However upon deletion a red line and green faded circle were left in the spots were the geometry was previously.

The second problem is this: Over the last hour atleast 3 times, the pane for navigating the model (which I have on the left side of the screen) would cut in half laterally.  It would look like there is 2 menus, but only one was able to be worked in.

Ctrl+R and the Rebuild functions did nothing.  I closed all open files (2, 3 at max) and this temporarily remodied the problem.  I even did a complete reboot of the program to no success.

These things are not hindering my performance, but they have raised my concern of course.

Thanks guys in advance.
