Windows application icon blinking at task bar when it starts - want to disable this

Question

Hi,

We have 1 windows application developed using .NET 2.0.
We have created a MSI file to install it on another machine and its installing successfully.

After installation when we starts the application a login screen appears but focus is not going on user name field. Only user name field appears highlited with default name and application icon blinks at task bar.

We want to stop this blinking and wants that after start of application the focus should directly go into user name field. This is happening on some windows XP Pro machines but on other Windows XP Pro m/c (which is VMWare image) its not happening.

Please some one help to fix this problem.

Thanks and Regards
