What's Wrong?

I use Claude for my legal practice. I have the same problem every session. I run into an image limit, or block limit, or it just stops and won't send my prompt, it just pauses, then resets my prompt back to the text box. It's very frustrating to have to catch Claude back up to what it was doing every couple hours. I purchased the 20x, but that didn't seem to make a difference. I'm now converting all PDF's to word, and have had no more image limit stops, but theres always another reason to terminate a session. Is this fixable? Is there a way I can at least monitor my proximity to cut off?

thank you.

What Should Happen?

I would like to be able to finish a single case within a session.

Steps to Reproduce

This is a length and file limit problem. Upload a lot of PDF or images. You won't get far. The research and legal discussions can go on for quite awhile.

Claude is amazing at this. I just can't keep one session through to the end.
