- Drop a dimension in your drawing
- Select it
- Enjoy not being able to zoom in with your mouse wheel or nudge it until you pan your view.
I suspected it might be my machine, hence (BUG) is in parenthesis. 
What is your video card/driver situation?
4 machines out of 6 have this problem in our office. All nVidia cards, all different drivers.
Hmmm. OK, that’s interesting, I’ll have to try that on a couple of other machines here. Just place a linear dimension and then select it? Nothing else special going on? Custom display modes, plug-ins, something…? --Mitch
Nothing special. It doesn’t matter if it’s a parallel or perspective view. Just don’t pan or zoom right after you place a dimension (it only happens to linear or aligned ones). If you do, everything works as intended.
If I use macro where it selects the dimension after i place it - everything works as intended.
Just checked the rest of the machines. 4 out of 8 have the problem. It also doesn’t matter how you select it (clicking or box).
Hm. Not seeing that here so far. AMD graphics though.

Weird, not seeing here either. I have a Geforce GT 330M.
Nvidia K2000, normal behavior here.
In your video, there are multiple “PAUSE” on the commandline between steps of the dimension command. I don’t have those, are you sure you aren’t running some macro? Still don’t know why that would matter, though.
^ yeah I’m running macro to drop the dimension and select it afterwards, but it doesn’t matter 'cause I can deselect it, select it again and then I won’t be able to zoom with the mouse wheel until I rotate or pan my view. 3D pilot though works fine.
It almost feels like when I select the dimension the focus switches to something else… Properties Window?.. 'Cause when I click on the selected dimension again (shift the focus back into model space) zoom works just fine. Does it make sense?
Yep, that’s it. As soon as I turn off Properties window everything works just fine. Basically, when I select linear or aligned dimension the focus switches onto Properties window and I have to click inside the model space to return it there.
I don’t know if it matters, but I have two 750 cards each driving its own monitor.
Hi Asterisk- does it behave if you disconnect the 3DPilot?
-Pascal
^ Nope. The only way of “fixing” it that I found is to turn off Properties window, but that’s like poking one of your yes out. 
I wonder if anyone at McNeel was able to reproduce this behaviour.
