이름 : nicklee 제목 : Bug! Hi I've just come across a problem in Instance Monitor... After refreshing several times and/or clicking ‘Clear Content’ it stops responding to ‘Refresh’ and part/all of the graphs go blank. Then when you close instance monitor and start it again it stays blank and brings up an error message (‘A required resource was unavailable’) either when you try to logon to DBMS or when you move the mouse over the maximize button. Sometimes the error message doesn’t go away and you have to press Ctrl-Alt-Del and end task. However, when you close Orange and run it again, Instance Monitor seems to work fine at first but exactly the same error occurs.
