hm, it looks like the common aspect of these freezes is that a file-selection 
dialog is (about to be) shown. So probably the problem is related to that.

On startup, RKWard prompts you about disabling "native file dialogs", unless 
you have already done so. Have you answered "Yes" to this question? *If* you 
have not, please do so the next time you start RKWard, and try again.

So far I have only heard of problems with "native file dialogs", but perhaps 
the "non-native" variant has problems on other systems. Thus, if you see this 
problem after you have disabled the native file dialogs, try the following:

1) Enter
    rk.sessionInfo()
in the R Console. Find the line that reads "Local KDE directory" and open the 
given folder in the Windows file browser. Exit RKWard.

2) Navigate to the sub-folder "share\config", and remove / rename "rkwardrc" 
(this resets all RKWard settings).

3) Start RKWard again. Answer "No", when prompted to disable native file 
dialogs. Try any of the problematic actions you listed.

Does that fix the problem for you?

Do you have any connected tape storage drives (this was know to cause problems 
in KDE on Windows in the past, although, I thought those were fixed in KDE 
4.5.4)? Are you aware of anything else that might be "unusual" about your 
setup?

Thanks!
Thomas
