Hi, I have (Fl_Gl_Window) opengl window, and I have checked that 
hardware is capable of double buffering so I have set this my window as 
double buffered. Yet my opengl drawing code within draw() is still 
called even even if the content is static (and no explicit redraw() is 
called) and I just drag another window in front of this opengl one, so 
the double buffering seems not working.

Do I need to check within my drawing code that it needs only swapping 
buffers and should I call it within my draw() method? Or do I need to 
set something else too  - apart from setting mode(FL_DOUBLE)? Or could 
it be the problem that I have this window within Fl_Tabs?


I am using MS VS 2005, the cuttent svn FLTK (pre-1.1.8)  and Intel 
integrated GMA3100 grahics chipset.

Thanks,
Roman
