This happens just once for each editing context change. [2] Each time, OpenOffice (or is it X11? or is it the Java[tm] runtime?) takes *400ms* to *1100ms* to return the text found in the clipboard. Most other applications do that just in a few milliseconds. --> Why does XXE query the clipboard so often? * XXE needs to know when the contents of the clipboard have changed (the actual contents, not just the type -- text, image, xml, html, rtf, etc -- of the contents). * Java has currently no API which allows to detect such change. Thus XXE has to query the clipboard once for each editing context change. * XXE needs to know when the contents of the clipboard have changed because it is a *validating* XML editor. Example: - You have selected a DocBook para. - The clipboard contains a DocBook programlisting. You may paste it after the para. - The clipboard now contains an XHTML pre (there is no data flavor change here: was XML and is still XML). You may no longer paste it after the para. --> Remarks: * With Java 1.5 instead of Java 1.6, XXE crashes in the middle of Sun's code. * I was not able to reproduce the problem with Java 1.6.0_11 and OpenOffice 3 on Windows.
