tab switching box

[CodeBlocker]

Hello,
i don't want this gray box to appear on pressing Ctrl+Tab:

Why not just switching to the next tab? This is the expected way, as i know it from Firefox. Is there any way of disabling the box? I haven't found anything in the settings.

I'm using CodeBlocks 12.11 on Windows. Maybe this is fixed in version 13.12?

Thank you in advance!
