Hello,

Can you disable the touchscreen in Windows 10 [1] and on the browser [2] and see if it resolves the issue.

Steps to Disable Touch API:

Chrome:

- Type chrome://flags/ in your browser

- Search for Touch Events API

- Set it to Disabled

Firefox:

Type "about:config" into the address bar of the browser, click the "I'll be careful, I promise!" button and scroll down until you find "dom.w3c_touch_events.enabled" ....when you click this item, a dialog box will appear that allows you to change the value of the setting.

disable=(0) enable=(1) auto-detect=(2).

Write 0 to disable it.

Regards,

Vishu

Re-install AEM into another folder and try again. I cannot reproduce this issue. There are files or libs missing from your current AEM system.

Hi Scott,

I have tried installing AEM into another folder faced the same issue there also.

Vish Dhaliwal's solution worked for me. Seems there is some existing issue With Windows 10 touch screen enabled desktop.

Found another post with similar issue : issue with OOTB Rich Text Editor (RTE) in 6.3

Please let me know if there is any code fix is available from Adobe for the same issue.

Hello Anupam,

I am glad it worked

Hybrid devices are not supported in 6.3 [1]. The fix is to disable Touch API.
