Since Tixati 3.20, the main tabs are shown overlapping

What OS?
I run both linux and win7 and have not seen this.
Is v3.21 the first time you had this problem? v3.19 was fine?
maybe post this in the main forum to get more people looking at this.

The failure is not determined by the operating system or paranormal phenomena.

The size for the label of these tabs is fixed, as a consequence in other languages the text does not fit inside the non-collapsible tab.

A Spanish proverb: "No hay mayor ciego que quien no quiere ver"

The solution is simple: make the tab banks resizable, as happens in the main window, which works well.

Plizze -> please repost those last 2 images with all files/filenames blurred.

Just tried all the versions from 3.29 back to 3.19. The last properly working version is 3.19. All versions after that don't resize the tabs and as a result the translated text is cropped/cut.
