Listbox Problem

J

J Streger

I have two listboxes in a form. I have set them up to move data from one form
to the other via buttons (the list items are removed from box one and added
to box two and vice versa). This all worked beautifully. Then I set up
dbl-clck events for each listbox, so the user can double click on an entry to
move it to the other listbox.
this works fine, except after the code is done running, the top value in the
listbox they selected and the value directly under the value they selected
are now selected.

If I run the code stepping through the lines, this doesn't happen at all. I
am using the exact same code for the button to move a value as I am for the
double-click. I even added a method to forcibly deselect all values in the
listbox, yet they are still selected.

Is this a bug in the listbox code itself? Anyone else have this issue? Below
is some of the code I use. These are the only methods that affect the
listboxes, as the others may read from them but do not touch the values.
Thanks.
