Hello Holger,

My guess (I just read your message, and did not test anything) is that your second subroutine does not take into account one case: when the user ticks on the menu, a 1001 event is triggered and your loop ends when g>0. Overall, any event will be with a positive value (except for few special events), so the execution will exit from this subroutine.
Furthermore, checking only for g>0 is not very good, the application will not exit in case the user presses the Home button in the second form, and this is what he is used to and expects (unless you want him to really look at this window and take an action).

So, here is how I would write the 2nd subroutine (there are other alternatives, reusing the e variable for example, which is my favorite way of doing - but I will stick to using the g variable):

_secondform:
savescreen
openform 200
' commented following line
'g=0 => not needed, doevents will return
' 0 if ever there is no event,
' same thing with e=0 in the
' first subroutine
repeat
g=doevents
if g=201 then
closeform
restorescreen
' added following line
g=-999
end if
' added following line
if g=-1 let e=-1 ' program will
' exit smoothly
until g<0 ' changed sign
return


That should make it.

Cheers,
aldweb
