Taskbar flashes when application starts

Hi group,

I wrote a VB.NET window application in VS 2005. It is running on WinXP SP2.

When I start it running, the splash screen shows and then the applications main form shows. This is all correct. Then my application in the taskbar starts to flash orange. It flashes on, off, then on again. The applications main form then looses focus.

I am having a problem finding why this is happening.

Any suggestions

Added comment - It seems that when I don't use the splash screen startup, this issue does not present itself.

    I will partially answer my own question.

    I disabled events while the application was initializing and during form_load. I enabled events at the end of the form_load process.

    All is working OK now. I still do not understand what events were happening and I am unable to trace them.

    I had the same problem. I found the orange flashing would stop after the main form got back the focus so at the bottom of the Splash Screen form load event handler I simply wrote: mainform.show()

    On second thought that a bad idea. The can cause the main form to open twice.

    Sorry
