Insert Row from the Edit menu. Unable to insert more than 15 rows.

[burokio]

I am using Countinuum for VisualBasic components to integrate with VB. I need to insert rows into scrolling window of the Sales Transaction Entry form(if it matters). The only way I found I can insert rows using Edit->Insert Row menu. And here I have problem, I cant insert more than 15 rows using Edit->Insert Row command. The behaviour is very strange. I can add 16th row by using mouse or keyboard, but Edit->Insert Row command says "You cannot insert a row".

Is there is a way to insert rows into the scrolling window using VBContinuum other then using
ExecuteSanScript("local boolean result;result = Menu_Invoke(MENU_ACTION_INSERTROW);&quot
code?
Or maybe there is a workaround or something I can do with GP settings?

Thanks in advance,
Shurik.
