Listview item disappear after a fwe seconds

[Efo74]

Hello everyone,

I have a strange problem with a Contact program that i wrote. The listview that I have created in some pc's compare regular and, after few second disapper all items. If I re-query the items return correctly.

This problem happens in some PC with different hardware configuration and with differend software configuration.

In My pc the program is working normally (Win8 x64), and in other pc also (Windows XP / Windows 7 x64).... but other with Win7x64 or Windows Xp have this prolem.

First question:

This problem has already happened to someone else?

How can I troubleshooting this problem ?

You start by posting your entire code, or a reproducer that demonstrates the issue.

If you cannot reproduce it, then you will need to post the entire real code, because that will be where the problem lies.

In my system I can't reproduce in any way the problem also in a VM with Windows 7 x64

1. Try to make a sample small program with huge ListView (fill it with random data)

2. run them on different PC's 

3. If this problem occurs then show here screenshots and this your sample code.

this small script should espesially show what you mean here: "If I re-query the items return correctly."
