While rotating the view using the middle mouse button sometimes my model will suddenly disappear upon releasing the button. Most of the time it works fine but this disappearing act occurs enough to drive me crazy. I can get the model back into view by zooming or selecting another view. It's not an inadvertent double click of the button as that zoom function works as expected. Any suggestions would be appreciated. Thanks.
Is your middle mouse wheel very sensitive? Perhaps as you release the middle mouse button you are inadvertently scrolling & zooming out your model from a position whereby it ends up off screen or very small. I used to get this with an old mouse until I got used to the feel of it.
In addition to what has already been said.
The last mouse I found that was good to use with the "middle button" combined with a scroll wheel to rotate was in 2004, if I remember correctly.
I always buy mice with more buttons and program a button on the side for the "middle button" and use my thumb to rotate. Currently using Logitech Performance MX.
But when this happens: hitting the f (zoom to fit) button on the keyboard will get you back on track.
Glenn, Kevin:
Thanks for your suggestions. While trying a new mouse I finally stumbles across what I am doing. Occasionally I would click on a visible sketch in the model. Sometimes these can be small and the effect is worse when viewing the sketches on edge. I think SW tries to reposition the view off the sketch and throws the view out to left field. If I hide all the sketches the problem goes away. I'm not sure if I fully understand it but at least I have a fix.
I don't remember anyone posting about it, so I suspect there's something wrong on your end. Have you tried it with another mouse? And while I've never heard of this particular issue, unsuitable graphics cards can cause some strange behavior. What are your system specs?
