Hi All, My Appian Designer is acting up. When I am trying to drag and drop

Hi All,
My Appian Designer is acting up. When I am trying to drag and drop any nodes (eg. Scrip task/ User Input Task) onto the designer from the designer palette, the node just disappears. This is is a new found problem, I am experiencing suddenly. I have restarted my system, logged out and logged back in and I also tried deleting the browser history. None of them worked.
When I try the same thing in the same environment, from a different PC, it is working. So puzzled on what the issue is?
