One problem I have noticed with the Sleep() function in VFP is that
it appears to put all VFP applications on your machine to sleep at the same
time.

I noticed this when I wrote an application that sat in the notification area and
checked for a valid internet connection every 30 seconds, this app tried to connect to www.microsoft.com and if succesful changed the icon to a green one and if not it would go red. After checking it would call Sleep(30000). I noticed that when this program was running I could only type in the VFP IDE during the brief moment that the program was actually doing the checking.

Just my two cents.
