For some weird reason, the File/Open and File/Save As dialog boxes are coming up way too wide on my system.

I run a dual-monitor setup, with monitor 1 (the primary monitor, on the right) at 1920x1200 and monitor 2 (on the left) at 1280x1024.  When the dialog boxes pop up, they are at least 1000 pixels wide.  There is a ton of "dead" white space used by the Name column, which makes correlating it with the modified date and the preview window difficult without manually resizing the window each time I open a file.

Even more inconvenient, I tend to keep the main GIMP window close to the left edge of the primary monitor screen, and about a quarter of the dialog boxes' width is actually displayed on my secondary monitor, with the boxes split across the screen.  Since the GIMP doesn't save the positions of the dialog boxes, in order to be useful, I have to manually move the dialog box over onto the main screen each and every time I want to open and/or save a file.

The GIMP didn't exhibit this behavior in the previous version (2.2.17) that I was running, and I uninstalled and reinstalled the program when I installed the 2.4 version.
