Dialog opens properly in winxp, but Freezes in win98se

"MyDlg" is a dialog class derived from CDialog
"pg_price" is a derived CPropertyPage

on pressing a button pg_price(derived from CPropertyPage), domodal is called

Code:

void pg_price::OnBUTTON() 
{
	MyDlg MyDlg_obj;
	MyDlg_obj.DoModal();
}

OnInitDialog of MyDlg (derived from CDialog):

Code:

BOOL MyDlg::OnInitDialog() 
{
	CDialog::OnInitDialog();
	return TRUE;  // return TRUE unless you set the focus to a control
	              // EXCEPTION: OCX Property Pages should return FALSE
}

now, the problem is that on winxp there isnt any problem. MyDlg_obj.DoModal(); displays the resource of MyDlg

but on win98se, the whole application hangs and become non-responsive upon clicking the button
MyDlg never appeared

so i ran a debugger and found out that the application has no problem running up to "BOOL MyDlg::OnInitDialog()" and returns it without any problem. I hit "f5" again and the application hangs. no assert/buffer overflow problems error messages were given, the whole application simply hangs there. i believe that's because the user interface thread got into something it cant get out of

doing a "step over" on the debugger in win98se i got the following

i really got no idea how this happened
how is it possible that this app works well on winxp but not win98se?
i need that application on win98se platform

using vc++6.0 SP6
win98se/winxp

please assist

Perhaps you run out of memory.

perhaps...
but i dont think so
winxp and win98se are ran on the same computer (with 2 different drives)
i also ran the same program on other independent computers (my friends') and it gives the same result

most likely it's the main user interface thread got stuck some where and hence the application freezes
i got no idea how to address this problem

after some research, i discovered that because the button was located on a CPropertySheet and the domodal is launch from it
this CPropertySheet is one of the pages in the tabs area
this tab area is on my main dialog

anyone have problems doing domodal on CPropertySheet ?
how to solve this problem?

problem solved

there's a stupid bug in MFC CPropertySheet for win98se
can be fixed by shifting keyboad focus away from any control objects on propertysheet
::setfocus( topwindow_hwnd)
