Well, in case anyone else also has this problem, I'll post my solution:
PHP Code:
temp.origposition = GuiScrollCtrl.scrollpos;
GuiScrollCtrl.scrolltobottom();
temp.maxposition = GuiScrollCtrl.scrollpos;
if (temp.origposition[1] < temp.maxposition[1])
GuiScrollCtrl.scrollTo(temp.origposition[0], temp.origposition[1]);
An unfortunate work around, and doesn't always work, but seems the only way.
