Add scrollbar in Form GUI

Hi

1. I used the following command to create the form. If I remove attachmentList from hiCreateAppForm, then I can not resize the form using the mouse to stretch the top right or bottom right.
2. I want the scrollbar is added to the form if the content is more than window size.

3. According  to Article (20429314) Title: Adding attachment list to a form removes scrollbars if content exceeds window size: How to create resizable forms using the hiCreateLayoutForm and hi*.layout functions  in Cadence support site, attachmentList field would disable scrollbar.       
If I comment out  attachementList in hi CreateAppForm, then I cannot stretch the form at all. I do not want to recode the form using hiCreateLayoutForm and hi*.layout functions if possible.

4. Please tell me how to activate scrollbar if the displayed content is more than the window size.

hiCreateAppForm(
?name 'bcmRunLVSForm
?formTitle strcat("Run LVS")
?fields
append(
list(
; x:y width:height field
list(libName 20:20+35 810:35 promptWidth)
list(cellName 20:55+35 710:35 promptWidth)
list(layoutViewName 730:55+35 100:35 0)
)
allPowerList
)
?callback "bcmRunLvsCB()"
?initialSize list(920 950)
?minSize list(920 950)
; ?attachmentList attachList
);hiCreateAppForm

Thanks
