AutoCAD Map 3D 2013 - PLINE Command looses viewed features

[Anonymous]

Hello all,

I'm facing a strange problem. I have a DWT file pointing to an Oracle DataSource (via FDO), with many layers and features.

I draw a line with _PLINE command, but during the drawing, when I zoom/unzoom, all layers suddenly disappear and features are not anymore visible. Sometime, they are just flickering. That's very strange and annoying.

Can someone help me please ?

What kind of information can I bring to be maybe more accurate ?

I'm using AutoCAD Map 3D 2013, with SP1.
