#954 secure desktop with multimonitor setups fails


When enabling the secure desktop feature for password entry with multimonitor setups, the following happens:
1. only the main monitor is locked and dimmed
2. sometimes no monitor is locked at all, but KeePass seems to be trying to do so, since it is absolutely insible and non-reacting to global hotkeys. The only chance to remedy this is to kill the application via task manager and starting it again.
This may have to do with DisplayFusion Pro intervening during the autostart sequence, but even if so, I would expect KeePass to lock _all_ monitor securely and independent of any other running applications.

    As a data point, I have two monitors, and have secure desktop enabled and I haven't encountered any issues like the one described.

    I also had a problem when I enabled the Secure Desktop feature while using 2 monitors.
    Only the main monitor would lock and dim just like what happened to Traveller.
    The secure desktop password entry box would then appear, but would only stay visible on screen for a second before disappearing, not long enough to type my password.
    The only was to enter my password would be to type it somewhere else, then copy it to the clipboard so that I could paste it into the secure desktop password entry box before it disappeared. Doing this defeats the whole purpose though, so I had to disable the feature.

    I'm not able to reproduce these issues (on a Windows 8.1 system, without DisplayFusion Pro). Some other application might be interfering with the desktop switching; see

    The only minor issue I encountered was that only the primary screen gets a dimmed background, all others have a solid blue background. I've now enhanced this: dimmed background images are now also displayed on all non-primary screens. This doesn't have any effect on security though.

    Here's the latest development snapshot for testing:

    Thanks and best regards,
