[CONNECT] Startup delay using MS_DISABLEWINDOWGHOSTING?

Hi all,

We use the MS_DISABLEWINDOWGHOSTING variable to avoid the "not responding"  windows message when running processor intensive processes, but am finding that it causes a 30 second start up delay. Is this normal? Does anyone know why it would be behaving this way?

BTW im using MicroStation CE U13 and OpenRoads Designer 2019 R2

Regards,

Mark
