AR# 7494: FPGA Editor 2.1i - Radio buttons are blank when selected
FPGA Editor 2.1i - Radio buttons are blank when selected
Keywords: blank, selected, buttons
General Description: Why does the icon or radio button disappear when I try to select it?
This problem is caused by a color map swapping failure, which is controlled by another Bristol process called "windu_client". At the startup of any Bristol application, the program will spawn a windu_client process if it does not already exist. This process allows Bristol applications to do color map swapping among X-window programs.
In this case, while the color swapping process existed, it didn't respond to FPGA Editor for unknown reasons.
To work-around this error, you must simply kill the process and restart your application.
