I've been using the Arduino board and software for a few months and not had this problem until yesterday. The Program Notification area (http://www.ladyada.net/images/arduino/winblinkcompiled.jpg) in the Arduino 0011 Alpha software has mysteriously disappeared. Even if I type an error, it does not return. In addition to this, whenever I try to use the Serial Monitor, it doesn't appear and the software freezes (menu bar still works but most functions such as uploading, saving, etc. fail to work).
I've tried reinstalling the software and using Arduino 0010 Alpha but the problem persists. I've searched the forums for this problem but have found nothing. Hope you can help.
