I have a user that is having an odd session focus issue. When he logs into our application, the session active window goes on and off, even if application window is in the foreground, the focus switches on and off every second or so, maybe a little faster. it makes it impossible for him to do any work within the session or even work on other applications on his PC. I have not seen this before, I uninstalled and re-installed the client but to no avail. After doing some google searching and citrix KB i have not found this issue listed, though it may be my search terms aren't just right. Has anyone seen anything similar?
