I bought a Lenovo Chromebook a few weeks ago and installed Zotero after setup. Things were working fine until two days ago, when Zotero began to spontaneously quit every time I attempted to move items between collections. I have not found anyone with a similar problem -- it is not merely that the drag-and-drop attempt fails, but that the very attempt actually causes Zotero to quit.

This pattern is very consistent. I tried dragging and dropping different items from multiple collections, and the result was always the same. I have tried restarting the Chromebook, uninstalling Zotero, wiping all the data associated with the app, and reinstalling it, but the problem continues to recur. If anyone knows how to solve this, I would appreciate the help.
