    Title: Win 98 SE [2010-10-06]
    I was using version 1.0.7 with Win 98 SE
    but last version 1.0.9 doesn't even launch!!
    Maybe I could try the previous one with this new palette. Is it available for download?

    Title: New catch format (slight mod) [2011-03-13]
    I currently use 1.0.9. It is an AWESOME tool! However, the Decimal format (### ### ###) I need to run through an edit before being able to use in my applications that require RGB values this way (###,###,###) Is there any way to add this format to the list? (Like, Decimal-CD (Comma Delimited))

    Title: Will you add support for Windows 10? [2017-10-18]
    When migrating from Windows 7 to 8.1 there were no issues and CatchColor worked just fine. But since I switched to Windows 10 Pro there's no icon in the tray anymore. But I see CatchColor in the task-manager. However, it's not accessible. :(
    Waiting Answer
    Title: Display scaling [2020-11-09]
    Attention: On a 4k display Windows 10 sets 150% scaling by default. CatchColor does not seem to be aware of that and grabs the wrong pixels. In order to make it work, be sure to set display scaling back to 100%.

    Title: Feature request [2020-11-09]
    Would be nice, to have a setting to make the "Choose your color" dialog always on top. Also don't let it disappear automatically.

    Title: Attention! Does no longer work on Windows 11 :( [2024-04-27]
    Microsoft changed the actions of the mouse buttons on tray icons. Any mouse button now drags the entire icon in the tray making this wonderful tool useless. :(
