I am sorry trying to post this quickly but let me explain this a bit more... All the menus allow you to move them around but not the physics chooser. However it can be moved by dragging a menu on top of it. This should be disabled so that you can not drag a menu a top of it.

Heee, you're talking about panels, not menus here. And we need to know how you manage to do that, here I can assure you I cannot drag anything above a headless panel (like your 'physic chooser', but also materials list in mat buttons, etc.).

Enable a physics type then using the ... on top of ... drag it above the physics type chooser. I think this is what you are asking?

Yes, but I cannot get a normal panel above an headless one that way… maybe make a short video demo (to be sure I do not miss something obvious here)?

I'm also not able to recreate... maybe try the usual things: Factory settings, test with buildbot, ...

If you can open this requires internet explorer :(

Christ man, can't you use a usual format everyone can read? or youtube & co even???

can you point me to a free screen recorder?

I will use a series of screen shots

@Julian Eisel (Severin) factory settings does not change anything and I am using most current blender version blender-2.73- 8a28895 -win64

Does this help at all?

Well… no, since none of us so far could redo this. Did you try factory settings (--factory-startup command line option)? Might be an addon doing strange things with panels, or your startup file having some strange panel configuration…

I tried that but not from the command line. does it make a difference?

Command line does not make a difference

Does anyone need anything more from me?

Adding Campbell and Sergey to see whether they have more ideas here…

Read though the reports, & still can't make sense of it.

Seems like its related to the order of panels?

@Aaron Carlisle (Blendify), could you explain steps in detail?

@Bastien Montagne (mont29), the report needs more info but relax!
(no need to be grumpy).

@Aaron Carlisle (Blendify), some questions:

• Does it happen with any panel in the physics context?
• Does this happen in other contexts (i.e. are you able to move panels above "unmovable" panel in material, particle contexts)?
• Any chance you can test other computer or other OS (linux, osx)?

Oh actually! Nevermind previous comment, it's dead easy to reproduce the issue on windows.

I would not have ever expected this to be OS-specific… :/

Does Anybody need anything...I think you all answered your own questions

Adding @Martijn Berger (juicyfruit) For his windows 8.x computer just in case

This happens for other header less panels e.g. materials

Did not think this would be windows bug ether. i will add more info to the description
