Hi,  
since I have created a new form (list view) and added as related tab to an existing tabpanel, I get this strange display behaviour:

If I create a new related record with the “+” button:  
[attachment=2]sped\_pic\_2.png[/attachment]  
The tabpanel displays a screenshot from the main form??

Now I have loaded a picture into the media column:  
[attachment=1]sped\_pic\_4.png[/attachment]

And when I delete the record:  
[attachment=0]sped\_pic\_6.png[/attachment]

Never before I had this strange behaviour and I have no idea where it comes from.  
All other tabs and tabpanels (related) are working as they should do.

If I change the (main)record and/or the tab the display disappears.

Servoy 7.4.11  
Win 10  
Java 8 several versions tried

Does anybody have an idea how I can fix this?

Best regards

I have now detected that this problem occurs because of a set style.  
This is my style:

```auto
form, odd, even, selected {
	background-color: transparent;
	color: #000000;
}

form odd {
	background-color: #FFFFFF;
}

form even {
	background-color: #f1f5fa;
}

form selected {
    background-color: #808080;
    color: #FFF;
}

form.alternate odd {
	background-color: #FFFFFF;
}

form.alternate even {
	background-color: #e0e0e0;
}

form.alternate selected {
    background-color: #88c4ff;
    color: #FFF;
}

form.alternate1 odd {
	background-color: #ffffff;
}

form.alternate1 even {
	background-color: #ffffff;
}

form.alternate1 selected {
    background-color: #ffffff;
    color: #FFF;
}

form.alternate2 odd {
	background-color: #ffffff;
}

form.alternate2 even {
	background-color: #ffffff; /*#f1f5fa;*/
}

form.alternate2 selected {
    background-color: #e0e0e0;
    color: #000000;
}

```

Is anything wrong with it?  
I use this on many other forms without any problems.

Best regards
