Have Issues With Admin Theme After Cs-Cart Upgarde

Hi dears,

After we upgraded our CS-Cart MVE to the latest 4.9, we get some look and feel issues with the admin theme:


It looks like (z-index) css problem in the main menu.

Any advise please.

Which CS-Cart version you using? I did not reproduce this in 4.9.1

The upgrade was to 4.9.1
