COPY/PASTE problem

[rutar]

Hello!

In this video is shown what "strange" objects appear after copy/paste via clipboard.

1. Opened "talv.dwg",  INSERT block "rihtimine 3tee" with "explode" option enabled.

2. Trying to copy some objects via clipboard into the same file.

 - first try - no sucsess;

- second try -   some set of lines appeared, like "grass' hatch.

- third try - another unwanted shape - set of lines like two rectangles one above another.

Only these two unwanted shapes appear with this copy/paste via clipboard issue.

Somtimes no problem (like in video - opened new file, and pasting here - was sucsess), sometimes nothing been copied, sometimes those strange shapes.  

Also we have a problems with inserting of BLOCKS with this issue.
