 ; The splitter makes the IDE crash on 24.04. According to valgring it's some memory freed in scintilla
 ; which cause that, but it's unclear why it does crash in the help window and not in the session history
 ; as it uses the same setup (panel/scintilla and splitter)
 ; So for now, disable the splitter until we find a way to fix it (we could change the scintilla by webgadget
 ; and use proper HTML help, which would allow images and other enhancement)
 ;
 #UseHelpSplitter = #False 
 #HelpPanelWidth = 400 ; Fixed width of the Panel when the splitter isn't used.

 ; The splitter makes the IDE crash on 24.04. According to valgring it's some memory freed in scintilla
 ; which cause that, but it's unclear why it does crash in the help window and not in the session history
 ; as it uses the same setup (panel/scintilla and splitter)
 ; So for now, disable the splitter until we find a way to fix it (we could change the scintilla by webgadget
 ; and use proper HTML help, which would allow images and other enhancement)
 ;
 #UseHelpSplitter = #False 
 #HelpPanelWidth = 400 ; Fixed width of the Panel when the splitter isn't used.
