I should have added we do not always see the error either.
We see this on Windows Embedded, so I am guessing we are missing something on the OS image. However, we can't tell what is missing. Can you indicate what the error is trying to tell us? 00000409 doesn't seem to be a reasonable font name - can you tell from the error message what might be wrong? Is there any debug setting we might turn on to help find what in the system is causing this? As I said, it's probably something missing in the OS image, but it's hard to tell
At first, please check fonts registry keys: HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts May be some font has reference to non-existing file 00000409.
