Comodo IceDragon display problem in Windows 10 64 Bit

I am using Windows 10 v1507 build 10586(64 Bit) in my laptop. I have difficulty to download latest browser version updates from official website, so I downloaded 64 bit installer from 3rd party software downloading website . 1st I installed version, this version opens but not displaying, now I updated to version, now in this version automatically swithed to full screen, minimize and maximize works but bottom taskbar not showing during browsing. I know that there is no additional display setting available in IceDragon Browser, and currently no display settings are changed by me. Only I disabled animation effects of Windows.
