For combobox or droplist, the "bottom" value is not used in the same way.
In this case, the bottom value is the maximum size of the window when the pop-up list is being displayed. All other times, the combobox is automatically sized to be one element tall. If you have trouble where you can not see the combobox drop-down, then check the bottom value and ensure it is large enough.
Then I see a small black square opening under the box of about 2 units. If I increase this value, the black square still opens at only 3 units, until I get to 50 and it just disappears.
It could be the ZOrder-bug, which means that the combobox does open, but it is drawn behind the component selection object, so you can't see it. Are you using Win98 or WinME?
Well, you're right.
I have just gone back into the ini file and found STATE was blank.
I re-entered the list items, and re-ran the program, but it still doesn't work. I then re-opened the ini file to find that STATE is blank again.
It is writing to the ini file before the page shows.
