Xoom Screen Dims & Action is not Completed?

[craiknelizabeth]

Lately when I am taking some action on my Xoom the screen just dims & it doesn't complete whatever I am trying to do. For example I was going to move a downloaded file to Ever note and when I touch the "share" icon the screen dims and does nothing rather than bringing up the options of where you share the file.

Any help would be much appreciated!
