pause -1 "swallows" plots after set terminal x11

Dear all,

pause -1 "swallows" plots after set terminal x11.

Here is my test script:

show terminal;
plot sin(x);pause -1 "Hit return to continue";
plot sin(x);pause -1 "Hit return to continue";
plot sin(x);pause -1 "Hit return to continue";
plot sin(x);pause -1 "Hit return to continue";
set terminal x11;
show terminal;
plot sin(x);pause -1 "Hit return to continue";
plot sin(x);pause -1 "Hit return to continue";
plot sin(x);pause -1 "Hit return to continue";
plot sin(x);pause -1 "Hit return to continue";

The output:

   terminal type is x11

Hit return to continue
Hit return to continue
Hit return to continue
Hit return to continue

   terminal type is x11  nopersist enhanced

Hit return to continue
Hit return to continueHit return to continue
Hit return to continue

In the part after "set terminal x11" the second plot is "swallowed" (I coul=
d not hit return).

Here the information about the versions and COMPILE_OPTIONS:

With Gnuplot-4.6.7 (and also 5.2.6) there is no such a problem. I also trie=
d 5.4.rc2 with the same result as with 5.2.8.

Thanks for your help and best regards,
