My yahoo mail is very slow sometimes. When it is, I notice that IE8 is using 100% cpu. Using sysinternals process explorer I discovered the thread using all the cpu in IE8 has Flash in the stackwalk.
I upgraded flash from 9 to 10, but the problem persists. I'm about to edit hosts to block the flash content by redirecting the yahoo and ad click dns entries. Is there some easier way to get flash to behave?
The fix for the long run will be switching to gmail.

You can go under Options... to Mail Classic..., which will use the old Yahoo Mail program which is faster but not as pretty.
