--- Comment #2 from Qian Hong fracting@gmail.com 2012-04-11 10:19:42 CDT --- Hello, updates:
1. There are two workaround: a) If I enable "Emulate a virtual desktop", then I can cleanly close Dr.com after clicking (x) twice. b) If I disable "Allow the window manager to control the windows", then I can cleanly close Dr.com after clicking (x) twice as well.
If I right click on the title bar of Dr.com then click "X Close Alt+F4" from the popup menu, then Dr.com will quit cleanly in any way.
