yes they do. it's windows XP, by the way, and the initial wd is
 "C:/Documents and Settings/<user name>"
with "<user name>" replaced by the respective user name.

i have no clue.

i just meant that anyone can read the directory. i didn't test this too hard, 
but to me this looks like the file browsing dialog tries to access the wd, 
fails and crashes the whole application. i've noticed that aaron also reports 
the issue in a screencast and managed to work around it by running RKWard with 
admin rights:
 o http://www.youtube.com/watch?v=_SiDjap-m9o#t=1m07s

as this also seems to solve the issue, i assume it's some weird access rights 
problem. [and of course it's not a real solution to run RKWard with such 
privileges...]

well, since the solution here is always the same, the windows version of 
RKWard could have a simple checkbox to set this option, rather than typing in 
the function call. something similar could be done for the initial working 
directory, for all platforms and not as a checkbox, but as an input field with 
an optional file selector dialog. the second is not a fix, but makes it more 
comfortable to workaround (besides, i'd find an option to set the startup 
working directory useful anyway).
