Hello,

I cannot reproduce the problem. Please try composing a small sample to demonstrate the problem and send it to andreyz*devart*com, including a script to create server objects.

I sent you a letter with the test program and the database
error remained even after the upgrade components.

as shown by the disassembler problem lies in the implementation of procedures
in windows xp not running a procedure resulting in crashes.

Trying to understand what)))

Problem fixed.
In Windows XP SP3 this error is one of the updates issued over the past two weeks.
Removing all the updates for this period, the program started working correctly ..
But what kind of upgrade?? I do not know

You can try installing updates one by one to pinpoint the exact update that causes this error.
