Hello, [Running 1.1.6cvs against XForms 0.89 on Linux RH6.2] When the LyX window is resized and subsequently another window (must be from another application; e.g. xterm) is brought up on top of the LyX window, this will cause an extra blinking of the LyX canvas. Notice: The resize is necessary to cause the extra blinking. At first I thought it was my window manager (Xfce), but the same behaviour occurs with Fvwm and Mwm. So I suppose the extra blinking is a LyX (or XForms) issue. Rob.
