[INVALID] Windows don't appear in Windows Vista

[yyyhxm1]

in the desing mode i put visible in false and then i put a button with this code

protected void Button1_Click(object sender, EventArgs e)
{
    Window1.Visible = true;
}

in Windows XP don't have problem,

but if i use windows vista to compile the code i can't see the windows control when it is running.

I'll run some tests to try and reproduce this problem.

Do you have the AutoShow property on the Window set to "true"?

Example

<cool:Window runat="server" ID="Window1" AutoShow="true" />
