How do I resolve this error with regards to this splitter control.

Asked by coenewnes in VB Controls, Visual Basic Programming

Tags: Visual Basic, 6.0, Error Number -2147417848 has occured:"Method 'AttachObjects' of object '_ctlSplitterEx' failed"

I am trying to update an existing Visual basic 6.0 application that uses a splitter control. This is a random error. Sometimes I can run it 5 or 6 times and it will actually not error out. I have googled this error and done everything I can think of to try and resolve. I even installed Windbg to try and assist further and I get the following:
==================================================================================
(12fc.f74): Access violation - code c0000005 (!!! second chance !!!)

7c911639 8a4805 mov cl,byte ptr [eax+5] ds:0023:018b9d1d=??
==================================================================================
I believe that this refers to a null reference and that the memory at "eax + 5" is no longer valid.
HELP!
