Using Internet Explorer 8 on a Windows XP Professional (Version 2002 with Service Pack 3) to search our own catalog running Koha 3.01.00.061 hosted by PTFS any titles that include double quotation marks within the title show up in the results list as they should except that are NOT hyperlinked, so a user cannot click on the title to see the entire bib record. Easy workaround, of course, is to use Firefox. But we can't exactly force all our users to do that. The same search in the staff client through Internet Explorer gets a clickable title, so this is only in OPAC.
Created attachment 2499 [details] screen shot of results list; see first title
I tested this by creating a MARC record which included single and double quotes, but it worked fine me in Internet Explorer 8 (Windows 7). Tested in HEAD and 3.0.x.
I just confirmed Kurt's problem in his catalog -- in IE8 (version 8.0.6001.18702) the title with the quote marks is not linked in the search results. When I edited the title to remove the quote marks, and redid the search in IE, the title was linked. I put the quote marks back in, and the title again is not linked. Out of curiosity, I moved the quote marks to a different place in the title (around words in the middle instead of at the end), but it made no difference. Using single quote marks did work fine in IE, though -- 'Patron and Father.' rather than "Patron and Father." It works fine in Firefox either way.
To update, Kurt's system is running at an older code level -- the problem is fixed in later code. Until we get his system updated, the workaround of using single quote marks should work.
