That it does not look perfect on smaller sizes, does not mean we have to show the user an everlasting hint that their screensize is too small (and so even further annoy the user and reduce the sceen size by that). It is still usable, isn't it?

If you google "LimeSurvey minimum screen" size you will get directly to the requirement in the manual (btw, the chapter is titled 'Make sure you can use LimeSurvey on your website')

Anyway, maybe we can show a hint during installation if that would still your frustration about the futile bug reports. What do you think?

If it was just about esthetics I would agree with you. But at least some of these also affect functionality, or the perception of functionality where things are not visible unless the screen is larger. If someone views those on a setup where a larger screen is not an option they would not even know that Limesurvey actually works. The warning would make it obvious that, things are not working and here is why. I find errors less frustrating if I understand them, and what I would need to do to fix.

Showing this in the manual or during installation does not address the problem. It would if there were only superadmins and survey fillers. It's the middle group of people who generate surveys and send them out I am concerned about. I only support about 20 people like that, and still don't have a clue who will use it from their iPad or try to use it from their phone, or who has bad eyes and therefore runs their screen at a crazy resolution. Even if those folks would google the problem that they encounter, they would certainly not be googling "Limesurvey minimum screen size" because you would only ask that if you already knew the solution. They would be googling items missing (not visible, but to them they would be missing), or messed up GUI elements (actually, they likely wouldn't google those, and instead just curse me and possibly your team for an app they would perceive as cheap or unprofessional - no name calling, just devil's advocate from front line user perspective).

I can work with the solution you have. The reason I am still pushing this is to make LimeSurvey better.

Fix committed to master branch: http://bugs.limesurvey.org/plugin.php?page=Source/view&id=20614

Added warning after login.

@ttenbergen : what functionnality can not be used with a screensize at 1024px (for example) ?

What things are not visible ?

I always think LS seems broken but we have all accessible even in 800px.

Version 2.53+161004 released

Just found one. Version 2.50.1+160823.
When you make the screen narrow enough so the top row collapses into the three bar menu button, most other functionality doesn't pop into that menu, for example CPDB doesn't.

2.58 : break at ~760px : really ? Seems OK : less than 800px : allow to see survey quicly etc ... but for all feature need a bigger screen.

Split screen in windows environment while looking at instructions on other half. Not a luxury environment, I realize.
However, for completeness, would you not want that menu to show what was listed in the expanded menu before?
I think some of that may be going back to some users not using cpdb much. If I log into LimeSurvey I am as likely to have to look at a participant as at a survey. Possibly more likely, just because of how we use LimeSurvey.

Also, the sideways scroll bar doesn't enable when content exists off to the side.
Found in survey participant view. In this case it may not be a resolution thing. Zooming in and out also causes the problem. Would it be hard and/or unreasonable to make the scroll bar available?

Correction, sideways scroll bar works in Version 2.58.0+170104
