How Do I Stop HP X3500 Mouse Changing DPI Settings When I Hold Down Left + Right Buttons?

Question

I set up an email account with NameCheap that I use with my Django app. Below is my email configuration based on information provided by NameCheap

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'mail.privateemail.com'
EMAIL_PORT = 465
EMAIL_HOST_USER = '[email protected]'
EMAIL_HOST_PASSWORD = os.getenv('EMAIL_PASSWORD')
EMAIL_USE_SSL = True
DEFAULT_FROM_EMAIL = 'WebsiteTitle <[email protected]>'

Now when I use send_mail() django function (eg. after registration) it is like playing roulette - one time it works properly and sends out an email, another time it throws an error saying

SMTPServerDisconnected at /reset-password/ Connection unexpectedly closed

As if something was wrong with my email configuration.

Do you have any idea what might cause it or how to try to fix it or debug it? Is it more likely NameCheap or Django?

Solution

This is just a workaround, but following my suggestion in the comments to use the middle button instead of left+right, you could use an application called X-Mouse to achieve this.

1. Download and install the application.
2. Start X-Mouse and click Add under Application/Window Profiles.
3. Find and select your application and click ok. (Optional - if you want to keep the middle button working normally in other application, as opposed to changing the setting for the default profile. You should even be able to customize exactly for which windows in the application the rule is applied if necessary.)
4. In the right panel, for Middle Button, select Simulated Keys in the dropdown menu.
5. As custom keys, enter {LMB}{RMB}
6. How to send the simulated keytrokes: "3 During".
7. Finally click ok and then apply in the main window.

Your middle button should now work as left+right, in this specific application only. This is just a workaround, but I hope it might be enough to use this mouse without getting annoyed.

It is probably not possible to disable this feature of the mouse. Out of curiosity, which application requires you to press both buttons for more than 3 seconds? Could it be that this gesture is actually an emulation of a middle button and that you could use the wheel (which probably also works as a middle button when pressed) to the same effect?

@nitro2k01 - It is a graphical application which has different behaviour when holding down both buttons and moving the mouse to drag something. When doing so, the DPI is changed everytime.

It is a bespoke one for our workplace. Does not allow the mouse behaviour to be customised, so I require this to be disabled from the mouse.

What happens in this application if you use the middle button (the wheel) instead of left+right?

[Dot NET]

Nothing happens - it does not have the same effect.

[Sparky_47]

If this is an internal application application, I would suggest that you request that to be added as a feature if possible. Otherwise, I think it's very likely that this feature is hardcoded in the mouse and cannot be disabled. Ie, the DPI setting is happening all inside the mouse and doesn't involve the OS. Good luck, though.

That's what I am suspecting, however I was hoping that I could download some software which "overrides" the mouse commands.

There is no compatible software for this specific mouse. Are there any 3rd party software, or am I stuck like this?
