Hi all: Seems that due to a restriction in "not standard DHTML javascript window object open method argument values" could exist (and in fact exists (*) in some internet explorer versions, my 7.0.5730.13), an "informal behaviour" that avoids opening of MARC assistants in Internet Explorer (those that commonly open when clicking in underlined text '...' links at http://.../cgi-bin/koha/cataloguing/addbiblio.pl, for example). In order to be let's say "more than concise but less than exhaustive" , this is from mozilla developer site, window open: (...) strWindowName This is the string that just names the new window. Such string can be used to be the target of links and forms when the target attribute of an <a> element or of a <form> is specified. This string parameter should not contain any blank space. strWindowName does not specify the title of the new window. (...) http://developer.mozilla.org/en/docs/DOM:window.open#Return_value_and_parame ters ..."should not contain any blank spaces" seems to be a **must not...** in IE7 This is the list of files and strings I've found that seem to be affected in a 02jan07 (3.00.00.040) git snapshot (*): cataloguing/value_builder/unimarc_field_125b.pl: \"unimarc field 125b\"
