System Information
Win7x64 GTX660M
Blender Version
Broken: 2.70

Short description of error
If multiple windows are open (but same Blender instance), shift+click or ctrl+click on the unfocused one (to pan or zoom in a viewport for instance) will be taken as a simple click instead. It makes working with floating viewports difficult since one must focus the window first, then act.
Exact steps for others to reproduce the error
Pop out a new 3D view by shift-clicking the corner, switch from one to the other using click with any modifier key (ctrl or shift).

I had a fix for this but it broke on ms-windows for some reason.
https://developer.blender.org/T34255
Heres an alternate fix: T40059_fix.diff
... though its a bit odd to handle key-down events differently to key-up events.

@ideasman42, why not just go ahead with this fix? otherwise make it a TODO.
@ThomasDinges might be interested in testing it.

Still happening for me, both on Windows and Fedora.
Does it happen with both 2.75a release and latest builds from builder.blender.org?
Yes, both on Windows and Fedora, release and buildbot.
(Fedora with Wayland if that is relevant)
Can actually confirm the issue on Debian Jessie + KDE.
@ideasman42, do you have any inputs here?
I've committed 2 different fixes for this. Both times they caused issues for other users which I couldn't redo,
Infact this has already been reported and moved to TODO (#40155).
The last fix is still in the code, but commented out (
fd781c1095)I wouldn't mind enabling this at the beginning of a release cycle, then spend time/effort to get to the bottom of the problem... test on different platforms... whatever it takes.
For anyone interested to test, uncomment
USE_WIN_ACTIVATEdefine insource/blender/windowmanager/intern/wm_window.c.See also: #34255 #40317 #40155
Added subscriber: @JulianEisel
Tried the fix, doesn't work for me :/ (yes, I un-commented USE_WIN_ACTIVATE)
Adding After Release project to increase chance that we won't forget it ;)
Changed status from 'Open' to: 'Archived'
As was mentioned above -- it's a known TODO (http://wiki.blender.org/index.php/Dev:Source/Development/Todo/UserInterface#Events)
Surely improvements are welcome but better to have this happen outside of the bug tracker work. Thanks for the report, but archiving it now.

Not sure why's that assigned to me. Was mentioned as a TODO. Is fine if someone looks into this report, but then assign to self. And maybe change type from to a TODO.

I don't mean to "me too"; just wanted to point out that at least for some users (e.g. me) this issue basically breaks using multiple windows due to all the accidental incorrect mouse issues that come from it. The only way I can use Blender multi-monitor is to have one big window stretched across multiple screens, which requires window manager rules to remember the window position, and since the monitors are different sizes, awkward workarounds to handle that, etc. Thanks for any time you have to look at it.

I think a complaint like this (and similar) would go away with this on Windows: https://developer.blender.org/D13951, since the target window would (most likely) be focused when moving the mouse there and would therefore get all keyboard input messages.
I don't think changing Window focus on hover is a good idea. The amount of unexpected issues this can cause will compound over time. It's also inconsistent with pretty much most other multi-window software out there. Issue with modifier keys not working on first interaction should be solved specifically, not with a monstrous solution that has many side effects.

ALT not working in Blender 3.3
Industry compatible keymap. I hold ALT and tweak with the middle mouse button in different windows. Panning is expected, but sometimes works like moving objects
Switching open windows by shift or ctrl-click bypasses the modifier key and registers as a simple click insteadto Switching open windows ignores held modifiers on WIN32Re-opening this for Windows as
24f3cb9b5cremoved support for it.Although we might consider it a known issue and document it since I'm not sure this can reliably work on Windows at the moment.
This is still an issue under Wayland when using the D key for annotations. Pressing D when hovering the other window without clicking it first, or keeping D pressed when switching between windows both result in Blender thinking D is not pressed until D is released and pressed again.
@max-mustermann this is almost certainly a completely different issue (different platform, 10 years gap...). Please open a new report.
@max-mustermann could you please open a new report for this as it's not the same issue as the modifier keys being incorrectly reported (which work in GNOME & KDE).
