Mouse selection, box-select and manipulator widgets not working in Object Mode in Blender 2.61 onwards on a specific Windows 7 computer
Closed, InvalidPublic

Description

I'm experiencing a bug when attempting to select objects in Object Mode using the right mouse button and the box-select (B) tool, and manipulator widgets are not working in both Object Mode and Edit Mode.

Right-clicking on an object does not select or deselect it for almost all objects. Additionally, box select does not select objects. The only exceptions are lamps and speakers, which are both selected correctly by the mouse and box-select. All objects can be selected in the outliner, and are selected using circle select (C) and select-all. Meanwhile, the left mouse button moves the 3D cursor, but it does not work on manipulator widgets on any objects.

To replicate, in the default cube + light scene, right-click on the camera, or on the cube after selecting the light. However, I haven't been able to replicate this on any other computer.

In Edit Mode, right-mouse select appears to be working correctly on vertices, but transformation handles still don't work.

I'm using 64-bit Windows 7 Home Premium Service Pack 1, with Python 2.71 installed (but may not be detected). I have an ATI Radeon HD 5700 series card and an Intel Core i5 CPU. I've attached the other system information detected by Blender in system-info.txt. I updated my graphics card drivers to the most recent drivers on the AMD site.

I've reinstalled Blender 2.63 several times in 64-bit and 32-bit, using both the installer and 7zip version. When uninstalling Blender, I've used CCleaner to remove remaining registry entries. I've also tried installing Blender outside of Program Files and running it as Administrator. This hasn't been successful.

Inside Blender, I've reverted to factory settings, and checked that the control settings are correct - the appropriate entries appear to all read 'select mouse' (shown in screenshot). If I change 'select mouse' to be a keyboard key (I used Q), the same problem seems to occur: I can only select lights and speakers.

Switching from right-mouse select to left-mouse select does not remove the problem: with that change, left-mouse select fails to work in object mode in the same way as before.

I've checked some previous versions of Blender. The problems do not occur in in 2.49b, 2.50 alpha 2 and 2.60a.
In 2.61 and 2.62, I have the same problems as in 2.63. (In all cases but 2.50, I'm using the 64-bit Windows installer).

I've googled this with as many strings as I can think of, and apparently a similar problem has happened to some Ubuntu users (example: http://blenderartists.org/forum/showthread.php?179540-Can-t-select-individual-objects-in-Ubuntu... ) but I can't find a Windows example. The Ubuntu users I've found fixed the problem with a graphics card driver update or an update of Ubuntu.

this is a common problem with selecting when FSAA is enabled (OpenGL anti-aliasing), this setting needs to be disabled in your graphics card configuration.

There's definitely full screen antialiasing in the screenshot, so think we can close this.

Thank you! Changing anti-aliasing mode has fixed the problem.

I'm using the Intel HD Graphics 4600 and I have the same problem, maybe someone here can help me figure this one out?

@Chen Scheuermann (chensche): this bug report is a year old, better open a new one if you think there is a bug. But in general, try installing the latest graphics driver from intel.com, and turn off any special settings in your graphics card configuration. Do not enable any antialiasing, but use the option in Blender itself to do that.
