Subject Does anyone know why FB freezes with IBO access?
Author Chuck Belanger
Hello:

Below is a madExcept log of an error that happens regularly with my user
base, especially in 64 bit Windows 7 although this error is in 32 bit XP.

This is a specific example, but it can be almost any dataset anywhere in
the program. With these DB queries occurring hundreds of times during a
user session (used in patient setting by alternative medicine
practitioners), any particular user may only experience this 1x per week.

The app is compiled in Delphi 2007 and uses IBO 4.8.7

Thanks,

Chuck Belanger
