STEPS TO REPRODUCE
1.  launch Rconsole in Windows terminal (or powershell or anything like that)
by typing in `R.exe` and view a function help page like `?lapply`
2.  open Rconsole in rkward and view a function help page like `?lapply`
3.  the help page were supposed to show up in a help browser tab within rkward.
However it shows a dialog  with a message of "source:
http://127.0.0.1:25141/library/base/html/lapply.html" and a progress bar, a
[pause] button and a [cancel] button.
4. by pressing the [cancel] button twice, it shows a dialog titled "Open in
default application?" with the message "The url you are trying to open
('http://127.0.0.1:25141/library/base/html/lapply.html') is not a local file or
the filetype is not supported by RKWard. Do you want to open the url in the
default application?" and a pair of [YES]/[NO] button.
5. if clicked [yes] nothing shows up, if clicked [no] the dialog simply
disappears and a help tab comes with a blank page shows up.
6. taskmanager shows a list of `kioslave5.exe` processes, these processes will
not end themselves after quitting rkward.

OBSERVED RESULT
dialogs in step 3 and step 4

EXPECTED RESULT
a help tab filled with the corresponding help text should be shown up within
rkward

ADDITIONAL INFORMATION
---Problem description---
Please fill in the missing bits *in English*.

Please give a brief summary on the problem:
help pages won't show up within rkward's help tab after viewing help message
launched from a Rconsole session run in Windows terminal session.

What - in detail - did you do directly before you encountered this problem?
Run a Rconsole session from Windows terminal and typed a command to view a
function help.
( The help page was launched by MS Edge browser)

When you try to repeat the above, does the problem occur again (no, sometimes,
always)?
always

If applicable: When doing the same thing in an R session outside of RKWard, do
you see the same problem?
it's hard to tell, the only R session outside of RKWard that I have engaged was
the Windows terminal session, and the default help browser for that session was
MS Edge browser.

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?
No

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)?
Windows 11 - install only for me ( the program files were located in my
personal fold)
