On some Windows 7 and Window Vista systems it never does that. Reproducible: Always Steps to Reproduce: 1. My extension (xpcom component implemented in DLL) have own window, 2. when it is being drawn it sends WM_PRINTCLIENT to main browser window to force it to draw into provided device context which is a DC of the extension's window. Actual Results: browser window is not drawn in responce to WM_PRINTCLIENT message. It happens on some systems only. Expected Results: browser window must process WM_PRINTCLIENT message and draw itself into a provided device context It does not depend on particual OS version and bits (have tried about 10 different combinations). I do not see any system, but seems that it depends on graphic adapter type. Everything works fine with Firefox 2 and 3, and with all Firefox versions including Firefox 4 beta 6 on Windows XP.
