I'm trying to do a simple click and drag with a mouse in a direct graphics plot window. The problem is that the cursor procedure accepts the DOWN click, but won't accept the UP click at the end of the drag. You have to do another DOWN click to get cursor to accept the next UP click. I've attached my routine which I've tested in a simple graphics window made using the command: "plot,[1,2],[1,2]". This routine works as expected in IDL without the need for the 2nd DOWN and UP click.
I'm using the fink package 0.9.4-1 of gdl with Fink 0.36.3, mac os x 10.8.5, and Xcode 5.0.2.
I'm using the macports library which I copied to /sw/share/gnudatalanguage/lib since it wasn't installed during the fink installation. The macports gdl wouldn't work since its plplot installation would not install the xwin device.
