I'm experiencing this annoyane with my wacom tablet. It's not really a wacom issue, the behaviour is the same with a mouse, but when using a mouse the pointer doesn't make a lot of uncontroblable movement.
When I select a valuebox I very often lose the focus because the mousepointer moved to the second screen for example (or maybe the top edge of the display). So you think you're typing a slick expression when actually nothing happens. You than have to move the pointer so that it hovers a houdini window so that you can finish typing some value.
For me to reproduce is really simple:
# Select a valuebox # Move the cursor to the second screen (or to top edge of the screen, so that it's in resize mode) # Press some keys > nothing happens # Move the mouse so that it hovers Houdini # Press some keys > now its working
So basically, if the mouse is not on top of a Houdini window you cannot type anything. It also does this if the window is still active.
Same thing here. Happens to all of us. I kind of got used to it. Dont think we can change it in any setting.
I am not sure if its really a bug or just based on the design of how houdini handels the focus of the mouse, But you could submit a Bug or RFE for that.
