Version 12 menu items

I have installed version 12.0.5 and the menus are not working by clicking on menu items, but only working by shortcut keys, don’t know why.
Please help if anybody knows.

bench update
and check it, most of the time it happens…
for me issue solved after update…

I do bench update, but still not working.

I do also bench build, and still have same problem.

Are you running this from a mobile device browser or from the app by any chance?

Because there’s a reported bug on those platforms. : Printing & Emailing on Mobile App, and on Mobile Browser & Creating, say, a quotation from lead on Mobile App, and on Mobile Browser - Version 12 · Issue #18554 · frappe/erpnext · GitHub

I followed the issue and its resolve and do the changes in bootstrap.css but nothing changed.
Still have same problem
erpnext version 12.0.6
frappe version 12.0.6
browser firefox version 64.0
on Linux ubuntu desktop 16.04

Found it.
If you make bench build after changing bootstrap.css that will be OK, otherwise make the change in file desk.min.css in the line of z-index in the paragraph below: change the z-index to 99 instead of 990.

.dropdown-backdrop {
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
z-index: 99;

That solves the problem immediately.
Thank you

Where is the location for this file :desk.min.css ?

It was solved two days ago not merged jet:
