My WinForms app has a simple modal login form, invoked at startup via ShowDialog(). When I run from inside Visual Studio, everything works fine. I can just type in my User ID, hit the Enter key, and get logged in.
But when I run a release build directly, everything looks normal (the login form is active, there's a blinking cursor in the User ID MaskedEditBox), but all keypresses are ignored until I click somewhere on the login form. Very annoying if you are used to doing everything from the keyboard.
I've tried to trace through the event handlers, and to set the focus directly with code, to no avail.
Any suggestions how to debug this (outside of Visual Studio), or failing that - a possible workaround?
Edit
Here's the calling code, in my Main Form:
private void OfeMainForm_Shown(object sender, EventArgs e)
{
OperatorLogon();
}
private void OperatorLogon()
{
// Modal dialogs should be in a "using" block for proper disposal
using (var logonForm = new C21CfrLogOnForm())
{
var dr = logonForm.ShowDialog(this);
if (dr == DialogResult.OK)
SaveOperatorId(logonForm.OperatorId);
else
Application.Exit();
}
}

Didn't think this was relevant, but I'm using Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase for it's splash screen and SingleInstanceController support.
I just commented out the splash screen code, and the problem has disappeared. So that's opened up a whole new line of inquiry...
