Forums Scripts & Popups Focus on ID problem

I got problem trying focus on tab with id 4, when the dialog appear, it always focus on the default tab 1! What's is wrong?
dialog agent {
tab "Position", 1, 8 10 290 100
tab "Animation", 2
tab "Loop Anim.", 3
tab "Speech", 4
}
on 1:dialog:agent:init:0: {
did -f agent 4
}

No idea why it doesn't work but

worked for me.

This is kind of hidden in the help file but it appears under Tab Control just after the sample dialog table.

You can use /did -fu to set the focus on a specific tab, and /did -vh to show/hide the entire tab control.

I tried using -fu, still would not work! Another weird occurence is that when I clicked on id 4 tab, it appear to be "hanged" on the dialog.

It works using the timer as indicated! I wonder if the script is being executed too fast, as I've similar problem on /editbox until someone recommend me to a 3rd party script called /sleep.
