I installed an Auto-update last night and haven't been on CU much tonight till now. Only in CU, my Enter key has stopped working. It's fine in Windows Mail but on CU, there is no response. This is with IE. FireFox is ok. Another weird behavior is a misspelled word is automatically underlined which never happened before. And ever since the update last night, the screen colors in certain places are slightly different. Has anyone else seen this??? Very weird...
