RAM disk update

As Big Mike pointed out, my linking from the db folder to individual files within a db folder on the RAM Disk did not make any sense. And eventually, the link to Ninjatrader.Old.sdf DID break again....

Using different software now

Computer was locking up to the extent that could only be turned off with the power switch. Seemed to happen when doing a lot of web browsing with Ninja open. Browsers would lock up first, then Ninja,...

Putting the cart before the horse won't solve the problem.

Have not given much thought to disk caching software since I am already dedicating two USB memory sticks to Windows Ready BoostŪ.

If so...
