List and Tree Object issue

[Orpa1]

Hey guys! I've been making a music application for sometime now so far so good, but I've been having some sort of a bug I noticed recently appreciate your help:

The application runs, asks for a folder the first time using an INI+ object.
The Application uses a Tree object to view the folder, each MP3 Selection auto plays the song.
A search option, searched the song/filename by the text that you type there, double click on the found song/songs plays the song, and select it from the tree object(Of course the searched directory=tree object directory), Now here is the issue:
Some specific songs won't be selected in the tree object for unknown reason!
It's about 10%-15% of the songs with that issue.
From what i've checked that's not a problem with any kind of symbols, numbers, other language or sub-folders, it's something else. Thanks any helpers!

Hey, we can't help you here if you don't provide any example mfa. :P

The main idea is,User double-clicks on an item from the list object, an Item that is working and available on the tree object, Most items works specified files, aren't.

And for the example file, it won't prove anything without adding all my 4000 songs directory LOL, to check it.

Please post some screenshots so we get to know what you mean exactly. Also post screenshots from the event list! editor so we see your code fot the object too.

The item in the tree object has to be visible (the parent folder needs to be open) if that's your problem...

As I said the bug is selected file from the searched results list and then select it on the tree object not working for specified files, so you wanted pictures here they are, thanks all helpers!

It's not sub-folders issue as I said, Because other files it opens the specified directory from itself.

RickyRombo thanks man!
Look guys, it's true what I said most files did found themselves but I thought about what Rickyrombo said and, what I did was for each file clicked, it's starts a loop based on number of folder, until it opens all of them, and now it opens all the files!

Thanks everyone!
Solved!!
