A newly created split screen does not have the same color-coded keywords as the original single pane text file.
This occurs if the DISPLAY variable is set to <host>:0 instead of <host>:0.0.
This issue conflicts with another display related issue on Linux RH5. For Bristol applications, like PACE and FPGA Editor on RH5, the DISPLAY setting must be set to :0, instead of :0.0, in order to eliminate a WINDU display error.
A possible work-around is to use the Tcl console to set the variable, depending on what application will be used.
For example, type "set env(DISPLAY) ":0.0"" to use ISE Text Editor and use split screens with same color-coded keywords.
To use PACE or FPGA Editor, type "set env(DISPLAY) ".0"".
