I can confirm it happens with me as well, typically when dragging something within a program such as Mendeley or OpenOffice. Toggling Num Lock key does indeed solve the problem.
** Description changed: Binary package hint: unity On all 3 systems where I have installed Ubuntu Natty I've seen this bug. At seemingly random points in time, the Unity launcher will stop autohiding, obscuring both maximized applications and "windowed" applications that sit under the launcher. I'm typically running Emacs and Opera, so perhaps this combination is relevant. Today I've discovered that toggling the Num Lock state on the keyboard makes the launcher hide. This seems to make no sense, but it is what I observe. Found no likely duplicates that were still open. unity package is at 3.8.12-0ubuntu1 ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: unity 3.8.12-0ubuntu1 ProcVersionSignature: Ubuntu 2.6.38-8.42-generic 2.6.38.2 Uname: Linux 2.6.38-8-generic x86_64 NonfreeKernelModules: nvidia .proc.driver.nvidia.gpus.0: Error: [Errno 21] Is a directory: '/proc/driver/nvidia/gpus/0' .proc.driver.nvidia.registry: Binary: "" .proc.driver.nvidia.version: - NVRM version: NVIDIA UNIX x86_64 Kernel Module 270.41.06 Mon Apr 18 14:53:56 PDT 2011 - GCC version: gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-8ubuntu4) + NVRM version: NVIDIA UNIX x86_64 Kernel Module 270.41.06 Mon Apr 18 14:53:56 PDT 2011 + GCC version: gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-8ubuntu4) Architecture: amd64 CompizPlugins: [core,bailer,detection,composite,opengl,decor,mousepoll,vpswitch,regex,animation,snap,expo,move,compiztoolbox,place,grid,imgpng,gnomecompat,wall,ezoom,workarounds,staticswitcher,resize,fade,unitymtgrabhandles,scale,session,unityshell] CompositorRunning: compiz Date: Wed May 18 12:48:58 2011 DistUpgraded: Fresh install DistroCodename: natty DistroVariant: ubuntu DkmsStatus: nvidia-current, 270.41.06, 2.6.38-8-generic, x86_64: installed GdmLog1: - + GdmLog2: - + GraphicsCard: - nVidia Corporation GT215 [GeForce GT 240] [10de:0ca3] (rev a2) (prog-if 00 [VGA controller]) - Subsystem: ASUSTeK Computer Inc.
