In Windows, the control z (undo) command sometimes does nothing. I’ve noticed a few other posts with this problem (including one on Mac and one unspecified) but no apparent resolution.
This can show up at any time. I’m not undoing complicated operations; sometimes I delete a word or line by mistake and try to immediately undo, but pushing control z or trying to undo through the edit menu does nothing. The option isn’t greyed out under the edit menu; it simply has no effect upon clicking.
I’m not sure if this has something to do with a very large file. I’m writing a dissertation and chose Libre Office over Word due to the increased functionality with Zotero. But the file is now hundreds of pages long with hundreds of citations. Is this related?
