lyx_mirror/src/frontends/qt4/GuiInclude.cpp
Richard Heck dc9146d250 Patch from Vincent van Ravesteijn. 
I noticed that for instance the Hyperlink Dialog loses all information when clicking on the main buffer. The same occurs with the Include Child Document Dialog and probably also others.
Do you agree on this being less intuitive ? If so, I included a small patch that will fix this for the two dialogs mentioned. I just adapted them to the design of the GuiGraphics Dialog.
