mouse wheel scrolling doesn't work on block diagram or front panel

[MGKandziora]

Hello All,

I've recently gotten an HP pavillion notebook with labview 8.5 installed running Vista32.

For ease of use, I've attached a Microsoft mouse for editing.

Problem is the scroll wheel doesn't work to scroll the block diagram or the front panel.  It works fine to scroll through the help listings, but not for editing.

Also, using the scrollwheel in a multicolumn listbox always reads as scroll up regardless of the direction the wheel is turned.

I've contacted hp and they report no issues with the notebook.

Since the issue is only with labview, no other application, I'm thinking that labview does something 'special' with regards to the mouse scroll wheel.

I sure would like to be able to use it for editing, since grabbing the scroll bar is extremely cumbersome and time-consuming.  Didn't help at all when I was taking the CLD test. 😞

Hope someone knows a setting or work-around.

Thanks,

Michael

AFAIK, the LabVIEW scroll bars are native to LabVIEW, so they don't respond to scrolling in the same way. (If you feel they should, use the product suggestion center ;)).

The right way would be to keep the diagram smaller than the screen size. 🙂

Don't forget that you can also pan the diagram by selecting the "hand" (not the "finger"!) from the tools palette.

(even with automatic tool selection, you can just shift-right-click---select hand...pan..pan...pan ...tab (to go back to automatic tool selection). This is definitely faster than the scrollers.

Thanks for the info.

I do try to keep diagram small, but queue driven producter-consumer setups grow a bit.  I will use your tips on using the hand to scroll.  Shame, I was just starting to get used to the autotool. Good thing it's not too late for me to re-learn old habits :).

When I get a chance, I will check 8.2 on my XP machine.  If I remember correctly, scrolling with the wheel worked on that setup. 

In any case, I need to work on the notebook using your ideas. 

Thanks for the help.

And, you can sideways-scroll if your mouse pointer is positioned on the horizontal scroll-bar.

Hi Michael,

You can also hold down ctrl+shift+(left click) to pan around the front panel or block diagram.  This key combination basically brings up the Scrolling tool (the "hand")(not the "finger"!) But when you release ctrl and shift, it goes away.  So useful!

I have an HP Pavillion laptop with WinXP, LabVIEW8.2, and a Ligitech Trackman Wheel. The scroll wheel works great in the Front Panel, Block Diagram and Listboxes, etc.

I would suggest trying a different mouse/driver first. I'll test it again soon when I install 8.5.

Good luck!

Good info. This isolates it to the mouse or Vista.  I'll try a Logitec mouse next, but I suspect I've been burned by a Vista issue.

Anyone else running Vista on a Pavillion experiencing mouse wheel issues?

[MGKandziora]

Oh, fogot to mention.  The trick of using the wheel mouse to scroll through cases doesn't work either.  I confirmed last night on my xp machine running 8.2 that the wheel works to scroll the diagram, front panel and cases in case statements.

The Vista notebook issue is definitely the oddity.

My colleague and I just got new Windows 7, 64-bit PCs, and our mouse wheels don't scroll either the front panel or the block diagram as they should (LV 2011 SP1).

The wheel scrolls just fine in every other Windows application, but the best we can get is a slight jerk of the front panel if we spin the wheel very fast.

Has anyone else seen this in LV 2011 64-bit?

Hello MGKandziora,

Does it happen with another mouse? LabVIEW is the only program exhibiting this problem?
