Main window minimal height issue

I have set the “Minimal window height” to a hard value:


It has no effect on the final exe. User can manually roll the window up until only the title bar shows. Width works as it suppose too. Does not happen to all skins.

Could you perhaps point me to correct area in a skin .vsf for me to check? I ask you because can’t find an answer and can’t seem to get a valid one either.
