cloudcmd: No icons, double click is not recognized

Hi

I really love CloudCmd and use it almost daily. But starting a some versions ago (sorry, don’t remember which one, but a couple of month ago), I have a strange issue. I open CloudCmd and then double click on a directory (CloudCmd root is /). The directory opens and then I click on the two dots to go back again. Now, all icons are disappeared and when i double click on a directoy, nothing happens. This only happens with the root directory (/), if I go deeper, I can go back and forth without problems, but as soon as I open the root directory again, the icons are gone and no double click is recognized. The only thing I could do is to refresh the page (F5). Then the icons are there again and it works.
