Hello, I have a problem. I have some views in a window component. When it is shown, it works fine; I can drag and move it. However, when I change the browser (Chrome) view mode to mobile and vice versa, it does not move. This only happens in Chromium-based browsers; it works fine on Firefox. Thanks
Hello @Yryskul,
Unfortunately, I was unable to reproduce the problem. Everything works fine for me here:Code Snippet
Please give us more details about your browser version and Webix version you are using. It would also be great if you could provide a code snippet that shows the problem in our snippet tool. Thank you in advance! 
Thanks for reply @NatashaS , now I tested on your given code snippet and found the case to reproduce it.
Steps:
- Changed the version to Webix 8.0 GPL
- Toggle device view in Devtools
- Try to move the window by dragging it
- Resize the view horizontally
- Toggle device view into orginal view
- Try to move the window by dragging it
- Then error below occurs:
TypeError: Cannot read properties of undefined (reading ‘0’)
at Object._get_context [as context] (webix.js?12:6290:21)
at HTMLDivElement._preStart (webix.js?12:6469:29)
at HTMLDivElement. (webix.js?12:488:22)
Thank you for such a detailed report.
This bug was fixed in version 9.2: Version 9.2, What's New Webix Docs. The only way to solve described problem is to update to a version no lower than 9.2. We recommend updating to the latest released build (10.2.5, if you are using Spreadsheet - 10.2.6), since it minimizes the bugs known to us.
