When I copy a file it does not allow me to paste it until I have copied it twice. No difference if using right-click menu, edit menu on the top or ctrl+c. So if I want to copy a file I need to press ctrl+c twice and then I can paste it elsewhere. No matter which partition the file is located and reboot does not solve the problem. Any ideas?
To make the story short I figured out that this is somehow related to KeePass2 password manager and not Caja. I noticed that ctrl+c worked funny in LibreOffice Calc too (ctrl+c did not copy the formula which is the default, but two times ctrl+c did).
Seems like Caja and LibreOffice works just fine until I open KeePass2 and copy one password from there. If I close KeePass2 it’s fine again. Maybe I should try to downgrade KeePass2 because I don’t remember having this problem before and been using that manager for years. Seems like others are having problemsm too https://bugs.launchpad.net/ubuntu/+source/keepass2/+bug/1659159
Edit: Downgraded to 2.32 and now everything is fine.
