I would expect this to take some time, but not minutes. I'll see if I can make it quicker and if not, I'll have to add a progress bar.

Thanks, though wouldn't it need a progress bar no matter what? For those scenarios when someone tries to copy 5 million rows by 1000 columns for example.

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/ 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. ntoskrnl.exe!KeSynchronizeExecution+0x7db6 ntoskrnl.exe!ExAcquireResourceExclusiveLite+0x1eb5 ntoskrnl.exe!ExAcquireResourceExclusiveLite+0x1e4 ntoskrnl.exe!KeWaitForSingleObject+0x256 ntoskrnl.exe!ExWaitForRundownProtectionRelease+0x8de ntoskrnl.exe!KiCheckForKernelApcDelivery+0x366 ntoskrnl.exe!KeSynchronizeExecution+0x469c Qt6Core.dll!QAbstractItemModel::endResetModel+0x665 Qt6Core.dll!QAbstractItemModel::endResetModel+0x6fe Qt6Core.dll!QAbstractItemModel::qt_static_metacall+0x1f75 Qt6Core.dll!QAbstractItemModel::qt_static_metacall+0x1690 Qt6Core.dll!QAbstractItemModelPrivate::columnsRemoved+0x85d Qt6Core.dll!QPersistentModelIndex::QPersistentModelIndex+0x2a Qt6Widgets.dll!QAccessibleWidget::window+0xa91d Qt6Widgets.dll!QTreeViewPrivate::below+0x7be qwindows.dll!qt_plugin_query_metadata_v2+0x6eb3b UIAutomationCore.dll!UiaRaiseAutomationEvent+0x6ad2 ...
