Cannot resize textmaker/planmaker/presentations main window

[giorba]

I have a problem with FreeOffice 2021 on Linux Mint Linux Mint 21.3 Virginia.
I have a configuration with two monitors and when I launch Textmaker, Planmaker or Presentations the window of these applications is exaggeratedly large and cannot be resized vertically.
Also, the window widget to maximize it is not shown.
I tried to force the window size by editing the .ini files of the applications but it did not work.
How can I solve the problem?
Attached is the screenshot of Textmaker as it appears to me.

Thank you for reporting this problem, but it seems some problem related to operating system (Mint) and not related to FreeOffice 2021.

If you want, you can reinstall FreeOffice and then check. Otherwise, you can do some operating system level troubleshooting by help of online research.
