We just upgraded our application from VFP 6 to VFP 8 SP1. We have an update table structure program that opens and closes tables a lot of times. In VFP 6 we used to use views to restore the data environment but in VFP 8 SP1 (don't know if it changed in VFP 9) it wouldn't open up all the tables. So I changed the code to store the table information to an array and use the array to open up the tables. Here's the problem when I debug though the code it always opens up the tables but if I just let it fly it sometimes doesn't open back up the tables. We have this happen in atleast 3 client installs and 1 inhouse. The one inhouse is not running antivirus so I know that's not it. Any ideas? Known bug?
