Object reference not set to an instance of an object. Comments trying to replicate error clean start of qiqqa, only opened Kassahun 2021, searched for things I knew were in document I knew were highlighted (outside of qiqa in external pdf viewer) Were hyperlinks Were highlighted hyperlinks I knew were not in the document All with no issue Specifically keeps failing when searching for "Meadows" which is within a highlight and thus for sure in document. ***tried to replicate by opening up with clean qiqqa and searching for "Meadows" did not replicate Instead crashed searching for "the" (trying to see if a very common word would crash) ***crashed again searching for meadows from first page of doc, im wondering if it might be related to having to "snake back" to the top *** searched meadows (p7) searched effect ***searched again for "effect" from first page, it does occur after page 7 ***scrolled to bottom of document seacrched for effect crashed ("effect" does occur on page 10) Exception Tree
