Thanks for responding!
I couldn't get the problem to repro (reproduce), so I think it was just me and that the G100 was in "Run" mode. Oh well.

Here's the G100 Firmware Manual text on "Autoboot Time"
Auto Boot Time
If you enter a value above 3 (seconds) in this field, then the G-REX will automatically start the DLP
firmware after this amount of time, after it is powered up. Before this time limit expires, if you connect to
the G-REX with a web browser then the timeout will be cancelled. A minimum timeout is required to give
you time to connect in case something goes wrong with the DLP firmware.
If you enter a value of 0 for the timeout, then the G-REX will wait indefinitely in the download manager.
In this case, you will need to start a web browser session to the G-REX, then press the "Run Firmware"
button in order to start the DLP firmware.
It is recommended that you set this to 0 when trying out new firmware. When happy with it, set the value
to 3 or more so that the new firmware starts automatically.-Cheers!
