Strange characters in HTML5

[Brian]

Hello - I am getting a few complaints of some strange happenings using HTML5. Sometimes, a user will be typing in a note section inside of our software, within the HTML5 browser and suddenly strange characters will appear, such as "a C with squiggle lines under them". These strange characters are appearing all by themselves, when the user is not typing or even touching the keyboard or mouse.

It happens on a laptop, with no peripherals plugged into it. If the user opens notepad, word, email, or any other webpage, this doesn't happen, but as soon as they click inside of the HTML5 window these characters are automatically typing.

Has anyone else run into this type of issue? I am running Version 8.10.2.12. However, I have seen the same issues on 7.70.10.24.

Brian,

when I remember your emal from 19.12.2014
you wrote
>>>I have found the cause of the "y with 2 dots". Everyone that has reported this issue is using an HP Laptop with a finger print scanner. There are 3 .exe's that control it:
>>>DpAgent.exe
>>>DpAgent.exe *32
>>>DpHostW.exe
>>>Once I kill all 3 of these, the random "y with 2 dots" stop.
I think, this issue comes from same area, only this time you describe different character.
However, even if I have HP with finger print scanner, I can not reproduce it, may be because of lacking such specific hardware/software pair.
Something just fires keyboard events inside your browser, and without your particular problematic laptop it is not possible to find out the source of this issue to make any workaround.

Hi JW - thanks for the reply. I have encountered this problem on a couple other machines that do not have a finger print scanner. I agree with you that something machine related is causing this input. I wish I could figure out what! Seems all local applications and other webpages ignore this random input. However, our support tool notices this random input, as well as HTML5. I figured I would put this post online and see if any others are experiencing similar issues. anyone?

Code: Select all

Seems all local applications and other webpages ignore this random input.

Because other webpages/applications did not set JavaScript to fire on keydown/keyup/keyinput events.
However without access to such server from problematic client directly it is impossible to do anything. So if you wish that i find out where the issue could happen, so give me TeamViewer access to the client where the problem happens with access to the server.
