[PyMOL] which PyMOL to open?

Hello all,

I hate to ask a dumb question, but I need some seriously novice help. I 
just installed educational-use-only PyMOL (version 1.7.4.5, x64) on a 
WIndows 10 machine, and I'm trying to open the program from the Windows 
10 start menu. However, there are many choices! Does anybody know what 
the difference is between these options (like Tcl-Tk, Console, Quad 
buffer, Dynamic, etc.)? Or is there a handy webpage that explains the 
difference? I can't find anything in the Wiki or FAQ websites.

Thanks!
