Using fully updated Vista Home Premium.

I want to run an  .hta application automatically on login.
If I put a shortcut to the .hta on the desktop and then I launch from the
shortcut all is OK.

If I copy the shortcut into the user account startup folder and then logoff
and log in all is also OK

The system I am creating is for a Mutlimedia presentation. I want it to
autostart at power on. I created an autologon using 'netplwiz'. Without the
.hta in startup when the machine powers on it logs in - also OK.

However putting the .hta in startup, sgutting down and the powering on is a
different matter.

The system starts and logs in, then the side bar and bottom bar appear, but
the backgroung is neither the screen background nor my .hta - instead it is a
white background. Right click on the white and the whole screen goes white
(my .hta should take over the whole screen, however it does not appear).
ALT/F4 closes whatever is open and the screen returns to a normal windows
desktop. Tabbing round the screen does not activate any of the .hta content.

Weird.

I suspect this is because some service hasn't started up before the.hta
starts up

Any ideas/suggestions appreciated

I will cross post on HTML Forums/Windows Administration
