Oracle Forms

Hi i have a form which is of the size 800*600 so i use a scroll bar to go the bottom of the fom..i have a button at the bottom to call another form..when i scroll and press the button the other form gets called but the position of the next form is half way through(ie..the form is shown frm the position of the scroll bar with respect to first form)..i need the form 2 be shown fully from the first..how this can be done..


one more thing..


.i have a radio button in a MULTI-RECORD block..the user can select any row using the radio button and can open the details of the respective record using a button OPEN..in forms we have limitation tht all the radio buttons in each of the record is considered as single button..so when i click the first record the first radio button is selectd,when i go 2 the 2nd button and click tht also gets selected but the first button is not cleared off.....

so i wrote a logic 2 clear the buttons(ie the records which are above /below the selected cursor record,tht is working 5n..)

but here also when i selected any button the selection is happening fine..but the record i select just runs away 2 some other positon(ie .. as i traverse through the block frm first recrod 2 last record for clearing other radio buttons.)..the user here is blind folded...can this be handled effectrively???????????????
