Full Screen mode

Hi there
My computer always crashes when I open a Writer document and try to view it in full screen mode. Is this a bug? Win10; LO 5.1.3.2.
Many thanks.

Please try resetting the user profile, sometimes solves strange issues.

Usually it’s enough renaming/deleting the file “user/registrymodifications.xcu”, it affects all the options in Menu/Tools/Options, and the files “user/basic/dialog.xlc” and “scrip.xlc” are overwritten, additionally custom colors in “user/config/standard.soc” are lost.
