I discovered a way to consistently trigger this. I don't know if all these steps are necessary, but it works for me consistently this way.
Configuration: - Ubuntu MATE 20.10 - caja version 1.24.0 - Evolution version 3.38.1-1 Steps to Reproduce: 1. In Evolution, open the 'Compose Message' window. I have it set by default to 'Plain Text' editing mode, and attachment bar collapsed. 2. Open caja and navigate to the desired file. 3. drag & drop the file in the message body. This should result in the full file path URI being displayed as the message. 4. press `CTRL+Z` (Undo). 5. Now drag the same file again, over the message body, into the (collapsed) attachment bar. 6. Your mouse should now be stuck in DND mode, requiring `pkill caja` to release it. -- You received this bug notification because you are a member of UBUNTU - AL - BR, which is subscribed to OpenShot Video Editor. https://bugs.launchpad.net/bugs/402892 Title: Mouse cursor gets stuck in "drag and drop" mode Status in OpenShot Video Editor: New Status in X.Org X server: New Status in chromium-browser package in Ubuntu: Confirmed Status in firefox package in Ubuntu: Confirmed Status in rapidsvn package in Ubuntu: Confirmed Bug description: Binary package hint: rapidsvn When clicking on the Bookmark root or on one of the bookmarks below the mouse cursor gets stuck in "drag n drop" mode, blocking all keyboard entry and also mouse clicks for the the whole GUI (systemwide).
