UB mouse wheel zoom problem

[dbur]

Well, it worked for a few minutes and then is happening again, with both old and new mouse, and after unplugging and replugging the mouse and re-starting UB.

..sorry, the post button was slow.  I don't see how to delete a dup post.

I see what this behavior is now.  When centering is selected the screen centers when zooming, but not the cursor.  Thus it only works if the cursor is exatly in the center of the window when I zoom. If the cursor is not exactly in the center of the window the screen flys off in a direction opposite the cursor distance fromt eh window center.

When it's working the cursor snaps automatically to the center of the window when I zoom so that it is far more friendly.

What would cause the cusor to not snap to the center of the window when I zoom with centering selected?

I have tried to get the same behaviour but haven't been able to, I also tried a few old mouse peripherals we had in the storage. This is the behaviour you should see in the "Mouse wheel behaviour" section of the Global Preferences:

• If the "zoom workspace" and "center on mouse" are selected, you should see that wherever in your workspace your mouse pointer is located, the workspace will center to it first, then zoom (in or out).

• If the "zoom workspace" is selected, but not "center on mouse", the workspace will simply zoom (in or out) in the current view position.

When we read the mouse wheel action and mouse position we take it from the Windows system directly, is hard to determine why Ultiboard will decide to interpret it differently. Like I said in a previous post, when I saw that behaviour before was a result of a deffective mouse wheel. But as you confirmed, this is not your case.

I can't think of anything else at this point, other than suggest to repair your UB installation, or perhaps resetting the user configuration file. If this is becoming annoying, you may want to change the mouse wheel behaviour to scroll instead, and use the F8 and F9 shortcuts for zoom in and out respectively.

dbur,

Another suggestion I got from R&D is about your mouse driver itself (if you have the mouse driver from the vendor, can you switch back to the Microsoft HID driver?).   Perhaps you can change the mouse wheel properties to see if that has some bearing on this issue.  

I *sometimes* have some erratic behavior with my optical mouse if it is over a poorly reflective (or overly reflective surface), but the fact that it appears to work initially doesn't seem to help that theory.

What you are describing seems to be that the 'center on mouse' checkbox is not correctly getting the mouse back to the midpoint of the screen (did you perhaps change the monitor/screen size recently?).  What happens if you uncheck the 'center on mouse' button, does the mouse position / UB view still jump around?   When you hit 'Apply' when you change the settings and then go back or reopen UB, does the setting stick?

Both mice I have tried are MS Intellipoint mice and have updated the MS driver.  I could try and re-do that.

When centering is NOT checked it seems to mostly behave correctly for that mode, though that's not the mode I like.  Sometimes unchecking it and checking it again makes it work again for a little while.

I'm on a farbic faced mouse pad that has always been good for optical mice.

I have a dual monitor setup with UB running on the right side.  The right side monitor is larger & higher resolution.

My video is nVidia GeForce 9800 GTX+ and OS is Win 7 64 bit, AMD Phenom II 1100T processor 8GB ram.  I don't know if any of those things are part of the problem or not.

I tried updating the driver but that didn't fix it either.

Anybody else using Win 7 64 bit without having this problem?
