with the Enabler config, there is not away to do that.. you can however try pushing a reboot package along with the config.. This Package would need to be created in package builder, and pushed down at the same time as the config. this should reboot the device with out the user acknowledging the reboot..
in the package you would need to include a post install script with the following:
RebootType = Warm
(Cold / Warm) can choose one or the other
Reboot = Auto
Ultimately this appears to be a defect and would need support to further investigate this issue.. Please contact Wavelink support on this..
This has been escalated and reply from Developers suggest this is AS DESIGNED. I have come to the understanding that this is required on CE7 OS, and in order to avoid this the admin of this gun would need to configure Hide Taskbar through some other means. MDM or application.
