textbox sometimes acts a lil buggy, anyhow, try this:
GAD.GAD=Object.GAD(MyTextBoxHandle)
GUI_SCROLL_CUR(GAD,-14*1000)
GAD.GAD=Object.GAD(MyTextBoxHandle)
GUI_SCROLL_CUR(GAD,-14)
Assuming there ain't more than 1000 lines in the text.
GAD.GAD=Object.GAD(MyTextBoxHandle)
GUI_SCROLL_CUR(GAD,-14*1000)
GAD.GAD=Object.GAD(MyTextBoxHandle)
GUI_SCROLL_CUR(GAD,-14)
Assuming there ain't more than 1000 lines in the text.
