Please fill in the missing bits *in English*.
Please give a brief summary on the problem:
###Please fill in###
What - in detail - did you do directly before you encountered this problem?
###Please fill in###
When you try to repeat the above, does the problem occur again (no, sometimes,
always)?
###Please fill in###
Always
If applicable: When doing the same thing in an R session outside of RKWard, do
you see the same problem?
###Please fill in###
Do you have any further information that might help us to track this problem
down? In particular, if applicable, can you provide sample data and sample R
code to reproduce this problem?
###Please fill in###
After editing the .rkworkplace file by hand and adding in a valid path RKward
starts normally. Removing the path by hand triggers the bug.
I can provide an strace of the process if necessary.
RKWard is available in many different packagings, and sometimes problems are
specific to one method of installation. How did you install RKWard (which
file(s) did you download)?
