Hi Ron, pgAdmin III is suffering from the same kind of bug as the one reported by Stefan (#333157). As soon as (at least regularly) you do some selection and double click on words being selected you get a specific cursor and the whole graphical environment is unusable until you press some key sequence (see #350723).
Based on a discussion with the pgadmin dev team, I just did some test by relinking on wxWidgets 2.6.3 and I can't reproduce that bug anymore (I'll recheck and recheck but I wasn't able to freeze the app & the desktop after 10 minutes of double click... fingers are too hot, I must get some cold ;). If you want me to do some further checking, I'd be glad to help. I must admit I don't know where and what to look for. HTH, Raphaël P.S. Just in case I missed something, wxWidgets 2.6.3 used for testing was built and installed like this: ./configure --with-gtk --enable-gtk2 --enable-unicode --enable-mimetype=yes --prefix=~/tmp make make install cd contrib/ make make install
