Please, I am running windows 8.1 and Houdini Version 15.0.244.16

Now I have B hotkey problem (toggle single/quad viewport)
———————–
- it works fine in the camera view mode
- when select tool or rotate etc. is active:
- hotkey is not working
- I can “make it work” by pressing space+B
- I also want to use the “Use Alt Key for View Controls”
- even with the Space+B, it is not working well while editing:
- when I move my mouse between the views and try to toggle with Space+B (left / quad / right / quad / perspective / quad / ..)
- sometimes it switches into the perspective, although I have mouse over the right view, etc.
- sometimes I have to press Space+B more times
- sometimes I have to release Space and try it again



A little bit of sollution
———————–
- I mapped the (toggle single/quad viewport) to ALT+W
- I can use it even in the editing mode, but still it is not responding ok

Holding down Space or Alt locks focus to that particular viewport until you let go of them.

Thank you for the reply. But often even if I release all keys, the “focus” still remains in for example right, although I am already above the left. Then I try to Space+MMB move left view to “focus” it and the right view moves (although my mouse is above the left). Sorry for inconvenience, maybe a bug.

It is buggy with Alt, even with Space, even if I change the B shortcut to “Alt+W”

I am desperate. It is still buggy
I have noticed this. In edit mode (for example move or rotate)

When I press the ALT key, usually it works ok (makes the hand cursor)

But if it fails:
- edit handles (scale/move) disappear in the viewport (as they should)
- if I move cursor … the handles appear again immediately
- I think, that sometimes the cursor makes a little jump (20px up left) and then goes back
- although the ALT is pressed, the cursor is still an arrow (not the hand)

I have the Wacom Intuos 4 XL tablet.

Hi, 2016, I feel your pain))

Not sure if this was fixed in the latest versions. Having the same problem in 17.5.173
The key to this problem, as I understand, is that H assumes the viewport to become ACTIVE at MOUSE MOVE event. the *CAMERA MODE* is locked and B hotkey is inactive until user moves the cursor, activating the vieport.

I wanted to use my side mouse button to max/min the vieport. B and SPACE+B worked unstable because of the reason above.

SOLUTION
I used X-Mouse Button Control macro: {MADD:1,1}{SPACE}B
{MADD:1,1} - moves cursor 1px x and y
{SPACE} - activates *CAMERA MODE*
B - maximizes/minimizes the vieport

Works like a charm after a short testing.

It seems to be a little but very annoying bug.
