I installed a GPS app (Spot skylab-mobilesystems.com) on my 8820. The icon appeared on the screen fine. It ran okay.
Later I went to access it and the icon had disappeared. The desktop manager software says the app is there.
I've un-installed & re-installed the app.
I've re-booted the 8820, even removed the battery a while.
I downgraded the OS then upgraded and re-installed.
Nothing brings the icon back. Still the software says it is loaded.
Other apps load and display fine.
What is going on here? Anyone else run across this phenomenon?
