after thinking awhile about "to buy or not to buy" I've decided to buy the game, DRM or not

Well...seems it's been a too early a decision, seems the game still has bugs to be fixed and we are all beta-testers.
To the point:
I grabbed my XP computer, downloaded the installer and clicked "Install".
I have been pretty much surprised by not having the option of where to install the game - it is simply installed in the docs&settings. (How about the option is offered? I really never ever install any gaming software on C:\ and would appreciate to stay it that way ).
Then I was offered to run the game and, well...
...I could not type in my password, neither clicking on the pass line nor trying to get to it via keyboard helped.
I found a meta-fix, however - the start-up allowed to input the password for ca.3 seconds, so I typed it in Notepad, ctrl+V'ed it and pressed Enter.
What might be the reason behind this weird way of logging in?
Of course, I also met the problem of a black screen during the start-up in XP, but FULLSCR.SYS crutch worked. I must note that this problem did not occur under Win 7.
(PROPOSITION HERE - what if the crutch is added to the next fix by default at last?)
