Randomly stickign keys.

I can report the same problem.
My Keymouse recently (few months) start behaving in the same fashion.
A lot of keypresses or their combination are sent to computer.
It could result in
"thiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii"
or sending ctrl + z multiple times to computer.

Any Idea for fix?

This happens to me as well, using a keymouse track on windows 10 via USB.

I use my keymouse for 6+ hours a day, this issue comes up very intermittently for me. If I turn both devices off and on using the switch on the bottom, the issue usually goes away for a day or two.

This has since stopped happening to me. I don't know why, but i don't believe it's the hardware, as sometimes the only way to get the CTL or ALT to not be stuck is to press the key on my laptops keyboard. Sometimes it was the key on the key-mouse, but sometimes not. It seemed to happen after a windows update and perhaps thats what got it to stop for me. I can tell you that i tried everything i could find online, drivers, everything, and nothing stopped it, and this was happening like 30 times a day but only when actually typing and less than half the time it was a key i pressed (almost never press alt or ctl).

Are you on the latest version of firmware? What version of the firmware are you using? (Open KeyMouse software>Devices>Firmware Update) In the top right it should say "Version: # ". The latest firmware update is 72.

The latest software version is 2.02 for Windows and 2.56 for Mac.
If it is a previous version you can redownload the software to get the latest update. Some earlier versions do not auto update correctly.

Thank you, I just updated from 71 to 72. I'll report back if the issue with keys sticking returns.

& if I select "update key layouts (recommended)", will it erase my custom layouts?

"Update key layouts (recommended)" is basically the same as the "Save to KeyMouse Devices" button. After it updates the firmware then it will update the layouts to be the same as the ones that are active in the software.

The sticking keys is still happening, even after updating to firmware version 72 and performing a windows update 3 days ago. It's happened twice since the update 3 days ago. For example, I will press the 5 key, and it will type 55555555, then I press 4 and it becomes 555555554444444444 and continue adding 4s until I press another key. If I press backspace it continues to rapid fire backspace until I press another key. The esc key stops it until I switch the devices off and back on, then everything is fine for hours.

Again, this happens roughly once every 8 hours of use, so this isn't a major issue- but it's still an issue nonetheless.

I had firmware version 71 on the devices.
Interestingly enough.... When pressing "check for updates" the version of KeyMouse firmware (2.00)
it said, there are no new updates.

I will get back here with feedback if that helped.

The key sticking is still in place with firmware version 72 for me.

Since this thread came back to life, i thought i'd put an update.

I upgraded to the newer keymouse. (i dropped mine so many times, i was afraid they'd die and i'd be stuck), now that i got the new ones, this has never happened once to me. I haven't replaced a mouse button and it's been several times longer than in the old one.. It appears that they fixed that in the new one.

Love the new one, but one of the ways i used to use scrolling works different now, so i had to change that key mapping. Otherwise, it's better for me in every way. Love the back lighting!
