Objects disappear sometimes

Hi,
i found out a strange effect in dxf files. if i am working on a dxf, it happens that several objects simply disappear from screen.
If i reopen the dxf, or change any properties of the layer, the objects are visible again (sometimes).

Example: if i have a layer for dimensions and measurements, sometimes the measurements disappear. if i zoom out, the dimensions are shown again; but they are to small to read. if i zoom in again, they are getting invisible again.

using win 8.1, Librecad 2.1.3

Is this a known issue?

Yes. It might be fixed in the nightly-builds for Windows.
I think using auto-zoom will fix the problem.

Hmmm...

Autozoom makes it visible again, it works!
Thank you for helping.

But i am wondering, why i didn't use Autozoom all the time in such a situation  
Life can be so simple...
