I have pinned the Enpass icon to my Taskbar. I expect to click once to launch Enpass but if i click once i can see the UI brief and then it is gone like a flash. Next time i click, iow the second click on the Enpass icon, Enpass launches as expected. I saw this in build 220 and now in build 239.
Important:
This happens only when i have booted the computer. All subsequent launches of Enpass do require one (1) click. So to reproduce it, reboot the computer, warm boot or cold boot, and let Enpass start in the background and then click one on the icon you have pinned to the Taskbar.
Additional info:
If i install the desktop version Enpass launches at the first click. (as expected)
I can reproduce this on two different computers. (HP desktop Workstation and ASUS laptop)
