I see that the "Loading..." window is not in front when the IDE loads... not sure what we'll do about that.
If it's any help, this was originally a problem with both the Cocoa and FLTK drivers and was because the hidden MaxIDE main window was being shown when the settings are loaded, i.e. when the window was maximized or resized. Easy enough to sort out on these two platforms... Not sure about GTK though...
