Hi, I just found that the "ShapedWindow.rbw" example (from bigdemo) causes a Warning Dialog window to appear when you click the display button, saying: "Ignoring attempt to set cHRM RGB triangle with zero area". After some experimenting with shaped frames I cannot make this window not to pop up - this is very annoying, since I don''t want to click it away every time my application is run. Is there any way to get round it, or at least to suppress that? ruby -v: ruby 1.9.1p376 (2009-12-07 revision 26041) [i686-linux] Marvin -- Posted via http://www.ruby-forum.com/.
