I don't use WLM so I can't test it, but what happens if you use the arrow keys on the keyboard to arrow down to the next email in the list?
I do this all the time in Thunderbird. Highlight an email read it, then use the down arrow to select the next in the list.
By the way, I left the Spanish/Portuguese post above, in case you can read either.

After viewing and closing an e-mail, it still stays highlighted in blue in the inbox list which causes it to reopen when you select another message to view.
After awhile you can have so many messages highlighted that are re-opening that it can drive you crazy, can anyone tell me how to disable this function
