Web IDE sub menus not appearing

Hello I use Web IDE personal 1.53.1 trial on Win10 64 bit.

I was indeed able to 1) import app 2) create extended app 3) deploy extended app
So far, so good.

The problem I am facing is that "often" Web IDE loses the ability to display the submenus. Whether I click on the top menu bar, or via right click on the projects, none of the submenus for New/Import/Run/Git/Deploy would open. The problem is not reproducible. When this happens, I try all the usual stuff:

- refresh
- restart orion and browser, login/logout
- clear all browser history/cookies/whatever
- try different browsers

Frustratingly, "sometimes" this helps, sometimes not.

I add a screen shot of orion console, maybe somebody can spot a problem (What about those 'processLocks??)

Thanks for any hint
