Does this stop you from using Cursor

Yes - Cursor is unusable

Update:
As soon as I closed the Agents Window and restarted - Open Editor Window started working as expected.

People may be seeing this until they close the Agents Window for the first time.

It could be related to the problem I had on Windows - with Agents Window opened other Cursor windows had a problem with modifying Cursor’s cache files. I did exactly the same - closed Agents Window and restarted Cursor to make them working again.
