Tree Controls with weird errors that PLAGUE MY LIFE!

I am really getting annoyed with this thing and any help you can give me will be greatly appreciated.

I have a wonderful Tree/List control embedded on a view which will display an account structure in my app. On my computer it works fine and everything is groovy however when I tested it on another computer I get an error when I click or double click on any part of the tree. I can't seem to fathom why it will work on mine but not anyone else's computer. I have looked at exactly what DLLs the app is running and there is some difference from machine to machine but mainly things like KERNEL32.DLL (surely it couldn't been that).

I am wondering if it could be the Windows system DLLs that are causing the problem (in which case I have big problems) or if it is something simpler.

That you for your time,

Forever Everton.

Can you explain a bit more about the error.
Also are the computers running the same OS and same OS version?

is the version of comctl32.dll the same ?

I'll check. Thank you very much.

I have come across similar problems, though not with treeList.
I found that certain properties (eg extended style :Modal frame etc..) had funny effects of different PC.

The COMCTL32 versions were different in the WINDOWS/SYSTEM directory...I copied mine onto the test computer and the error was no more.
