Annoying mouse behavior in last few days

[JonathanLindsey]

Just in the last few days I started having an annoying problem with my mouse in LabVIEW. If I hold down my ctrl key or shift key or both in order make more space, area select additional items, or pan my block diagram and then move my mouse slightly, LV suddenly thinks I am pointing way off my screen.

Is anyone else seeing this issue? If so, maybe we should compare computer specifications, here are a few of mine that may be relevant.

Windows 10 Home, ASUS, 15" laptop screen with larger external monitor of same screen resolution (the issue still happens if I disconnect the external monitor).

I'm thinking it must me related to a windows or ASUS driver update because I have not updated LabVIEW recently. I only see the problem in LabVIEW.

Any chance your mouse has some 'clever' DPI switch? These can be used to make your mouse move 'faster' or slower, often via some toggle or perhaps a modal rotation through various settings.

If that's the case, it might be that the Ctrl or Shift (or Ctrl+Shift?) keys are some shortcut for this in your mouse driver configuration application (fancy mice seem to have these applications with perturbing frequency) as of a recent update or similar.

Especially if the 'toggled' value is very high or goes through several modes by holding the keys, that might explain your problem (although it seems a poor design choice if that is what's happening...)

Good idea but unfortunately doesn't appear to be it. I do have a button on my mouse that may be a DPI button. I pressed it more than 10 times, each time testing if the problem went away; it didn't. I tried disconnecting my external mouse and using my mouse pad; same problem.

I also tried changing my laptop's screen from 125% zoom to 100% and restarting my PC but that did not work either so I set it back.

When I hold down ctrl and drag to copy something or hold down shift to move something in a cardinal direction or hold down ctrl + shift and drag to copy something in a cardinal direction, there is NO problem.

I did a service request. They had me update my LabVIEW software and update Windows. I did these and still had the problem. They them had me setup a virtual machine to test if the problem would still happen. I did the VM last Thursday July 23rd and did not see the issue. Then a bit later I realized I was not having the problem on my normal computer. I have not had the problem since.

It's happened to me occasionally.  But worse than that, it often doesn't recognize button-up on the mouse; so when I left the button up, it's still dragging.  I have to re-click multiple times to get it to let go.

Maybe, just maybe:

A graphic card hot key? Or as suggested in that thread a broken laptop keyboard?

This might have happened after a windows update, but I find uninstalling it bad advice. Windows 10 updates tend to turn options on and off. I'd prefer finding which option it switched.

It would be interesting to know if this is just LabVIEW. And if you have this with both an external keyboard and the laptop's keyboard.

Hi,

are you using a docking station with your laptop?

I had seen similar behaviour with a docking station (connected by Thunderbolt) due to Thunderbolt driver problems: about once a minute the driver had a "hickup" and so the laptop didn't recognize keyboard or mouse events (keypress, mouse button, mouse move). The smaller annoyance were missing chars when typing, the more annoying behaviour was an apparently stucked CTRL/ALT/SHIFT key…

paul_cardinale's problem sounds a bit different than what I was having.

When I was having the problem, in some situations LV would gitter between my cursor being where it should be and somewhere way off my screen

I am not using a docking station. I have a laptop with integrated Intel graphics and a NVIDIA Geforce GTX 850M graphics card. I have a wired USB keyboard in addition to the laptop's built in keyboard but can't remember if I tried both keyboards (I probably did).

I have not noticed keys sticking.
