I updated to OS X Lion just after it came out. No problems at all with the upgrade. Recently, I applied the round of patches that came out supporting, I believe, various features and so forth of iCloud. Since doing these recent patches, I have noticed the following quirks and am wondering if you all have ideas on how to correct these things. MAC OS X Lion 10.7.2 iMac 3.4ghz i7 8G 1. The background login screen image on my iMac is now only filling the upper right 25% of the screen. It luckily shows enough for me to see the image I need to select to get the login prompt. Interestingly, if I move the mouse into the other 75%, which is only solid black, it begins to draw small little squares of the background where ever I move the mouse. Ideas? 2. Safari won't allow me to login to the AT&T wireless website. Once I enter the login information, it simply redisplays the login screen. I've used the account, after getting this error, on other computers with say Windows Explorer just fine. Ideas? 3. I have a Western Digital Live Hub, the 1 terabyte model. I used to be able to view it via the shared device selection in iTunes. Once I select the device it simply displays the "clocking mouse" indefinitely. This still works on my wife's laptop with the previous version of OS X. Ideas? All of these worked fine before doing the latest round of patches. Thanks for any help.
