"GraphMap"-App loosing painted functions ?.

[jackyjoy123]

Hello,

"GraphMap"-App loosing the painted functions (for exmple sin(x)) after changing board view
to document or desktop view!

Description:
I am using the "GraphMap" initialized with two functions sin(x) and cos(x) on my site
in board view mode. The functions were painted. So good.

But every time after switching to document view and going back to the board view the
"GraphMap" was loaded, but the functions disapperaed.
Same behavior under OS Win7 and OS Win 10. I could send some screen shots of that behavior.

Whats wrong? I am not shure, but I think it seems to be a bug.

thanks
