It looks like gnuplot freezes when the window is reactivated.

When I run gnuplot under gdb, I get the following backtrace when the window has freezed:

So the problem seems to be in a wxt_waitforinput() function (file wxterminal/wxt_gui.cpp). When the window freezes the loop starting from line 2856 keeps running. Any ideas why?
