How to start XiboClient from shell command?

Well this problem has been half solved by updating CMS and XiboClient to 1.7.8 now I can shut down the running XiboClient by Shell Command ‘taskkill /IM XiboClient.exe’ and I can
Maximize it by ‘/max XiboClient.exe’ however there’s a small problem, there’s a delay when I schedule to close or open XiboClient and this can be from 5sec to 4min, is there any way
I can eliminate this delay???
