I'm using this on Windows 11 and it's locking up trying to copy a single cell. As in, here's the entire repro:

1. Open Modern CSV.

2. Open any file.

3. Select any cell.

4. Hit ctrl-c.

Expected: The cell contents would be copied.

Actual: The program becomes completely unresponsive with high CPU usage and must be force-quit.

Happy to help however I can, because so far I really like this product and I want to be using it.

I've never seen or heard of this issue. By any chance, could you send me a file that it crashes on? That or a video showing the crash. You can send them here: https://www.moderncsv.com/report-a-bug/

Let me see if I can repro with a sanitized file.

In the meantime, I popped open Process Explorer. Here's a slightly abbreviated stack of the only running thread -- the rest are in waiting states. I don't know much about Qt, so this doesn't really mean anything to me. But it looks like it's maybe some sort of locking issue.
