Rick Schummer just blogged a compelling call to action for everyone to install VFP 9 SP2 and test it. He took the time to write a whitepaper that explains how to install SP2 in a different directory than your VFP 9 RTM (Release to Manufacturing) or VFP 9 SP1 versions. This way you can leave your production version (RTM or SP1) as is, yet still have SP2 on the same machine so you can test your applications.
I can tell you that I had already previously followed his advice and have SP1 and SP2 running on my machine without any problems. I encourage everyone else to do the same. Rick did a great job in explaining why you should do this so I'm just going to point you to his blog which also has the link to his whitepaper.
Please take the time to install and test SP2. If we all do this, the entire FoxPro Community, including yourself, will benefit!
