Viewing or closing an Report causes an GPF

Good morning from Italy!

Some of mine reports are causing an GPF when opening or closing them from my VB6 application; in the details of the Microsoft GPF Error Window - when it opens - I found the following dll's as crashing modules:

- cslibu-2-0-0.dll

- craxdrt.dll

- crpe.dll

- ufmanager.dll

- ntdll.dll

(when wished and possible I can post the screenshots).

On the customer machines runs Windows XP Professional SP3 (locale: Germany).

On my developing machine runs Windows Vista Professional SP1 (locale: Italy)

I'm using Crystal Reports XI R1 SP4 Developer Edition.

The reports are build on the Pervasive.SQL 2000i native connection combined with an <FieldDefinitionFile>, wich will be filled from the VB6 application through the <CrystalDataObject> Rowset.

Please note, that the crash also happens, when I replace the TTX file connection with an native Pervasive table or when I use an ADO Recordset to fill the TTX file (these test's I made the last days...

Sometimes also crash the VB6 IDE, indicating an Buffer Overrun Error.

Thak you for help!
