This didn’t used to happen, and I’ve been hesitant to report it because I’m sure it’s so annoying someone else was going to do it, but that doesn’t appear to be the case.
When I am typing in the prompt window to the AI Agent, if I use my standard shift + Home to select all the text and then hit Backspace, nothing happens.
I have to use DEL, and even then it deletes all of the text except the first and last characters.
Steps to Reproduce
Type a sentence in to the AI Agent prompt window.
Hold shift and press HOME
Press Backspace
Press DEL
Expected Behavior
I expect the text I just highlighted to be deleted.
Operating System
Windows 10/11
Current Cursor Version (Menu → About Cursor → Copy)
Now, however, the Agent is refusing to answer questions about what Model it is. Explicitly it is telling me it will not answer that question as if it’s some kind of protected information.
I ask because I like to confirm that I’m on the correct model - the smaller, “faster” models do not reason well, ignore directives, and write terrible code; I prefer to use GPT-5 High.
I noticed the difference right away when it didn’t take 10 seconds to think before replying to me, nor did it show its thought process.
edit
It looks like my model selection was ignored on the first agent window open; I had to close that window and open a new one to actually get any kind of model selection change working and back to GPT-5 High
What version of Cursor do you have installed? Also, have you tried checking if the same thing happens in other projects or in a blank Cursor window? I couldn’t reproduce it, so additional steps are needed to identify the cause.
The bug keeps coming and going, I’m not sure what’s going on. When I open Cursor for the first time, I can’t type in the agent field at all, and have to open a new chat.
The delete-not-working-bug is back now, and I’m on version:
The issue might be related to one of the extensions. Try launching in safe mode using this command in the terminal: cursor --disable-extensions, and check if the problem persists. Also, you didn’t mention if this happens in other projects or an empty Cursor window.
Here is another video of the strange behavior I’m seeing in the input window; It’s squished down because I didn’t want to show text from my chat, but it demonstrates the problems well.
