Delay action until process starts, throws error

I have a SR open for this but wondered if anyone has seen this.

As I'm sure a lot of people know, there is still a problem running nalwin on the Zen login event. We have to add a delay of about 10 seconds to ensure the window loads at all, though I do not understand why this is. On slower computers, even that isnt enough, so I tried to have the delay wait until explorer.exe has loaded before loading nalwin, so that faster computers wouldnt have to wait so long and slower ones could wait longer before loading nalwin.

Randomly, when the agent attempts to check the status of explorer.exe, it throws an error which is displayed in the log and the agent immediately crashes.
