Unintentional double-clicking is a common issue with gaming mice, usually caused by wear on the internal contact mechanism of the button. If your Mars Gaming MMR double-clicks with every press of the left button, here’s what you can try:
Diagnostic and Troubleshooting Steps
- Check with a simple test: Open a text editor and click slowly on the mouse button. If you consistently see two characters instead of one, it is indeed an issue with the internal switch.
- Update the drivers: Visit the official Mars Gaming website for the latest USB drivers for the MMR. An outdated driver can occasionally exacerbate this issue.
- Test in different applications: Confirm that the double-click occurs everywhere (games, desktop, browser) and not just in a specific software.
Solutions Based on the Condition of Your Mouse
If your mouse is still under warranty: Contact Mars Gaming support directly. Switch defects are recognized as manufacturing defects and are generally covered for 1 to 2 years depending on your purchase date.
If it is no longer covered: Unfortunately, the button contact mechanism is not repairable without specific technical expertise. Gaming mice have switches with a typical lifespan of 10 to 20 million clicks, and wear on the contact cannot be corrected by software adjustment.
