performance degrading with win32 version

[Manu TM <manutm007 gmail com>]

Hi!

I now have another question about the linux app ported to winxp. It's a 
ticker app that reads then renders a text file to a pixmap (a tall 
single-line image), then it kind of scrolls the pixmap by drawing a part 
of it to a drawing_area, using gdk_draw_drawable() within a timeout 
handler set by g_timeout_add().
The problem is it works fine on linux (the scrolling is really smooth) 
but the win version is choppy and flickering and uses at least 90% of 
cpu resources (vs 15% with linux.)
Does anyone have an clue? Is it related to some mingw config or threads 
or drawing_area or gtk for win?

Thank you.
