We are running idl 8.0.1 on an up-to-date Centos 5 (32 bit) Linux. When you run the program below with the "idl" command, it will plot but the graphics do not retain when put behind a window and the buttons don't work. If you remove the stop everything works great. Or if you run the program in "idlde" then things work great even with the stop. Does anyone have a fix or a work-a-round?
