Hi all, I have these 2 problems with my combobox and i just hope some of you can shed some light as to why they are happening...

define class myform as form
:
add object mycombobox as combobox with;
rowsourcetype = 6, rowsource = 'part.partname', style = 2
procedure mycombobox.init
set order to tag partname in part
endproc
:
enddefine

1) When the combobox gets the focus, i can press the Spacebar and the combobox's list will be dropped-down. I can then use my arrow keys to move up or down and make my selection of the part names that appear in the list by pressing Enter. But if i try to select a part name from the list using the mouse, i can but then i cannot use the keyboard the way i describe earlier anymore. The drop-down list from the combobox closes back if i try to press any arrow key. Anybody have any idea what is going on?

2) The second problem is, if i run the same program in another computer, i cant use the arrow keys to move up and down, instead, if i press the down arrow key, the list of part names in my combobox jumps straight to the last part name and then my program hangs. but i dont encounter the problem on other computers. Does this problem have anything to do with the hardware? The PC with the problem does have a lower RAM.

Thanks a lot

Susan
