Thread: Automatic exit from fullscreen mode

    Default Automatic exit from fullscreen mode

    Hello all,

    I discovered a strange behaviour with IrfanView 4.40 32-bit and I'm not sure if it's a bug, or a feature for which I can't find a setting.

    In the past, I have been semi-aware that IrfanView sometimes exits fullscreen mode without me hitting any keyboard or mouse button. Yesterday, this started to happen every few seconds. Back then I didn't have the time to explore it further, but did so today. The automatic exits still happen, but now it's once a minute.

    I tested this running IrfanView from different drives, using different mouses, and even on different computers (albeit both running Windows 7 and both having two monitors connected), but the behaviour was the same.

    I found that it doesn't matter when I entered fullscreen mode, the automatic exit happens at the same second every minute as long as I don't re-start IrfanView, and IrfanView is the active window. If it's not (that is, IrfanView is fullscreen on one of my screens and I work on the other screen), it will stay fullscreen indefinitely. To be precise, the auto-exit trigger period is more like 59.9 seconds: the second at which it happens slowly gets earlier.

    I looked but couldn't find a setting on such an automatic fullscreen exit, nor could I find others reporting the same behaviour in the forum. Can someone reproduce this? Any ideas on how to change the auto-exit period or how to stop the behaviour entirely? (Other than downloading the current version of IrfanView, which I can't do on my work computer.)

    There are a few official ways of exiting from fullscreen mode.


    1. Middle-click (quite easy to do by accident if using the scrollwheel to browse)
    2. Left-click in the top left or top right corner
    3. Press Enter.


    I don't know of any setting that will exit after one minute.

    I don't know of any setting that will exit after one minute.
    ESC, all keys but Num Lock and +/- on my numpad, and a couple of accented letter keys on my Hungarian-language keypad will also exit me from fullscreen mode. But what I describe happens even if my hands aren't anywhere near the keypad or the mouse, and having tried it with multiple mouses and computers and keyboards, it cannot be a hardware fault, either.

    Have you tried to reproduce this with your installed copy of IrfanView?

    Fullscreen is never ended 'automagically' here. I just had an image in fullscreen for > 6 minutes on the screen and had to end it manually.
    Internet-browsers also go to fullscreen if you press F11 (end with another F11), please see if the fullscreen of the browser will also be ended 'automagically'.
    I suppose that an app on your PC triggers the end of fullscreen in IV. Maybe the screensaver or something you installed recently.
