Obviously there the OK button is grayed out because nothing is selected.</P> <P>This is an old and reported bug - it was supposed to be fixed but is still present. If you look into the bug database of the previous bug I reported month</P> <P>ago I think you can trace it back to what caused it. They once found a reason - I think it was the dialog box / comand tool having a bad loop and</P> <P>RMB click stoped that loop.</P> Tue, 02 Jun 2015 19:22:38 GMT cekuhnen 2015-06-02T19:22:38Z
