Hi i was wondering if anyone else was having an issue where unity 5.3. Seems to install fine but when i start it up it just freezes up on the screen where you select the project. Restarted computer. Reinstalled unity several times . but everytime it froze up with a blank window. Using windows 10 64 bit. Reinstalled 5.2.3 and works fine again.. Guess for the time being i cant upgrade.
