I am experiencing an unexpected behavior when saving to file plots produced with Plots gr() backend, through the REPL.
When saving to file, the plot window on the screen disappears, and never comes back again when plotting new graphs (although saving to file those new graphs results in proper files with the expected plotting in them).
I found no way to get the plotting window back (I tried selecting a different backend and then choosing gr() again). The only way is to restart Julia.
On the contrary, with the pyplot() backend there is not such a problem.
Julia v. 0.6.2-pre.2
Plots v. 0.13.1
GR v. 0.24.0
Debian GNU/Linux v. 9.2 (current stable).
Thanks for suggestions,
