error on IE9

I’ve got a bug in IE9.
I checked the dhtmlxcommon.js and it is identical to the latest version of scheduler.
See the attached image


Can you reproduce this issue in our scheduler’s samples?
What files do you attach on the page (please copy your code).

What do you do to reproduce this case?

Kind regards,

Yep… I tested with the latest version and it is working :frowning:
My version is dhtmlxScheduler v30_111025. I will update it.
Thanks a lot!
