IPAQ 5500 Series .NET CF problems

[Paul W]

I have two .NET SDE applications that will not run on 2 different user's
IPAQ h5550 or h5555 devices. When the application is launched, a wait
cursor appears but the app never loads and does not appear in the running
programs list. The only thing that is remotely similar between the 2
devices is a 3rd party "Today Screen" application, but both "Today Screen"
applications are from different developers. The strange thing is the
problem can't be duplicated on other devices such as Dell or Toshiba (PPC
2003) or any PPC 2002 device with .NET CF installed
Technical notes:
Both applications have a splash screen that loads xml data and reads a
registry setting. The first time the app runs, if it does not find the
registry setting, it writes it. After the data is loaded and the registry
setting is read (or written), the splash screen is hidded and the apps main
form is shown using form.show().
Has anyone else experienced this problem?

What happens if you do a hard reset of the unit to set it back to the
factory defaults. Does it still have this problem? If not - there is a
problem with one of the installed applications interfering with yours.

I didn't want to comment on this until further testing could be done. On
our test device, installed out of the box the software worked, in fact we
can't get it to not work on our test device. Today an additional user
e-mailed and said the software will not run on his h5555 device. When
questioned about other 3rd-party software, he said nothing else is
installed.

On all other devices, the software works fine on either the RTM release with
the initial PPC 2003 devices and with SP1 installed. We installed SP1 on
the 2 devices we can get our hands on and it didn't help. Now there is a
third device where the software will not run, and the user claims no other
3rd party software is installed.

I am beginning to wonder if it has something to do with the biometric
software/settings on these devices.
