Unwanted »Sample Buttons And Forms« panel on start-up [Windows 10]

Hi @Klаus ,

that's unusual. You could trace the library file. It should be in the InDesign application folder:

Presets > Button Library > ButtonLibrary.indl

Don't know if you can or should remove it from there.

If you like trace the path to the file with this ExtendScript (JavaScript) when this InDesign library file is showing up:

( function()
{
if(app.libraries.length == 0 )
{ 
	alert("Message:" +"\r"+ "No open INDD-Libraries found!" );
	return 
};

var libs = app.libraries.everyItem().getElements();
var resultPaths = [];

for( var n=0; n<libs.length; n++ )
{
	resultPaths[n] = app.libraries[n].fullName;
}

alert( "Open Libraries:" +"\r"+ resultPaths.join("\r") );
}() )

What's your version of InDesign? 18.5.0 now?

I cannot see this behavior with my updated InDesign 18.5.0 on Windows 10.

But I can remember, that in an earlier version of InDesign some years ago, it happened to me as well.

Removing cache and preferences could help as well…

Do you use workspaces to control the panels activated and their layout on your screen(s)?
