Hi @squeetard, sorry to hear about your issues.
Regarding the “page up” issue, can you kindly check within the Tobii Core Interaction Settings what keys you have assigned to the various interaction functions, most especially ‘mouse warp’ .. I suspect there may be a conflict there.
If it turns out that no keys are assigned, certainly try for now disabling any of the interaction options to see if that has an effect. Failing that, it would certainly be recommended to ensure you have the latest version of the Tobii Core Software installed. If so, might be worth a quick uninstall and reinstall just in case some settings files have been corrupted.
With regard to the ‘configuring’ error.. might be worth trying a different USB port to see if that changes the situation, also can you check that your computer’s power settings are set to ‘performance’. within the system device manager, also ensure that the USB hubs are not set to save power when idle.
Kindly go through these steps and let us know how you get on. If you could also confirm your hardware and software specs in the follow up. Thanks.
