1). restart system with original start up disc, holding down "c" key.
2). using time machine restore from non "lion" operating system. this will kill p.o.s. lion.
3). once back in non 10.7 OS be careful not to install via software updates, sarafi 5.1
4). sarafi 5.1 like lion *****.
5). if you have sarafi 5.1, degrade by typing in this: support.apple.com/kb/dl1939
a). a very large software update that degraded my sarafi 5.1 back to sarafi 5.05
6). streetsmart.com and java worked fine for me after this fix.
7), also you can download firefox, and though slower than sarafi 5.05 it will load java, and stock screens.
GOOD LUCK. my first microsoft moment with apple in 8 years of chronic love for their products. time to
sell AAPL shares.
