IX developer and blue window border

[xsienix 0]

Dear all,

I'am using IX in combination with a Beier X7 Pro panel.
There are some valves on the HMI witch can be adjusted by the operators.
The can press the valve symbol and the settings appear as a popup on the screen.
Sadly with a blue window border in top of it.
I'am aware of a script that get rid of the border. I wrote the code in it, but no matter what i do, this border won't dissapear. 
I poke around with picture and canvas settings, no results either.

My laptop is using Windows 10.
IX Dev= version 2.4 SP1

What can i do?
