Backgrounds "flare"?

I suspect that the solution to your problem is to clear your cache manually.  With Second Life closed, go to the appropriate pathway and delete all the files inside the "cache" folder.

• Windows XP - C:\Documents and Settings\<username>\Application Data\SecondLife\cache
• Windows Vista - C:\Users\<username>\AppData\Roaming\SecondLife\cache
• Windows Vista Home Premium - C:\Users\<username>\AppData\Roaming\SecondLife\browser_profile\cache
• Windows 7 - C:\Users\<username>\AppData\Roaming\SecondLife\browser_profile\Cache AND

• Windows 7 - C:\Users\<username>\AppData\Local\SecondLife\ (Viewer version 1.23.5 (136262))
• Mac - /Users/<username>/Library/Caches/SecondLife
• Linux - ~/.secondlife/cache

If you are using more than one SL viewer, especially if one is V2 and the other is a V1 viewer like 1.23 or Phoenix, it's very important to use separate cache folders on your hard drive for each one.  Otherwise, it's easy for one viewer to bork images that the other has cached.
