You could try to reinstall glance.
1. Change your phone date 100 years forward.
2. Open the glance settings. It will tell you that there was a problem with the app, and it will let you uninstall it.
3. Install SysApp Pusher and reinstall glance from there.
Remember to change the date back afterwards.
Glance is not working properly for me either. I actually tried to uninstall it as I couldn't open the app, and although it disappeared from the list of apps, the glance background is still there and active. I now have no way of accessing the app, and when I try to re-install it, it says it's already installed. Thankfully I like the settings as they are, but it would be nice to be able to access them in case I want to change them in future...
Does the same date trick work for all Nokia apps? I know that's how I uninstalled the access point software.
Yes it does, I uninstalled touch,accessories,etc. You can uninstall all of them.
