Error in VB6 + ODC ??

    Usual sample (DBGrid+ODC) from ...\OO4O23\VB\Samples\DataCtrl or simplified variant (texbox+ODC):

1. runs with VB4 & VB5 in all cases,
2. runs with VB6 in the case of compiled .EXE,
3. attempt to run in IDE VB6 starts normally + shows data in the form, but after I try to navigate (buttons < or > or ..., or in program code) shows: Run-time error '-2147417848 (80010108)': Method 'MoveNext' of object '_IOraDynaset' failed or another fantasy.

     Some variants cause internal errors and abort IDE without error messages about OO4O.

     Tested with VB6 from MS VS 6.0 EE (with/without SP1+SP2) english, VB6 russian, Oracle for NT EE v. 8.04 / 8.05, OO4O v.2.2 É 2.3., NT 4.0 Workstation (SP3 / SP4).

     My friends had the same problem (returned to VB5).

    What to do?! Help please!
    (Maybe it was discussed long ago, but I am novice in Oracle).
