I have Matlab 2012a installed in my Linux Mint 13 XFCE. The Matlab program itself runs okay, but one strange thing about it is that the icon disappears from the taskbar after the program is opened for a while. The icon appears again if I restart Matlab, but then after some time it disappears. I still can access the program by "Alt+Tab", but I would like to have the icon always on the taskbar as long as the program is opened.
I find someone was having similar issues (http://www.mathworks.com/matlabcentr..._thread/267008
), and the issues were considered because of a bug of compiz. However, I haven't found a fix. Does anyone know how to fix it? Thanks!
