VC Net Application Fails on Win98/me

My Application ... compiled under VC6 has been in the field for 3 years running on win98 platforms.

I develop on Win2K

I recently upgraded to VC NET (only using VC7) - NO NET components or capability.

I have a Dialog box that contains a grid OCX I purchased from Componentone.

All is fine on my Win2k machine.

Win98/ME machines FAIL when attempting to DoModal()
on the Dialog.

File occmgr.cpp - line 410

Function --->

BOOL COccManager::CreateDlgControls(CWnd* pWndParent, LPCTSTR lpszResourceName,
_AFX_OCC_DIALOG_INFO* pOccDlgInfo)


Any Ideas????
