R devel - Apr 2003 - changing dir. to network drive crash Rgui on NT4 ( PR#282 8)

This is interesting: The crash does not happen if I run 
Rgui in MDI mode.  The crash seemed to only occur in SDI.

==========================================================For the record:

Under Rgui, using the menu "File / Channge dir..." to change 
to a network drive crashes rgui.  The crash happens if I 
browse to a folder on a mapped drive.  I.e., if I type in 
"q:\Andy" in the text box, it works, but if I try to browse
to Q:\Andy and then click on OK, that's when it crashes.  

If I do setwd("q:/Andy"), that works fine.  If I use the menu,
set dir to a local drive first, then use the menu again to set
dir to the network drive, that works, too.

Adding the --vanilla flag doesn't help.

Andy,

After seeing your note above and Uwe's follow up, I reset Rgui to SDI
mode (I normally run MDI).  I have not been able to do this
predictably yet, but I have locked up Rgui twice and caused it to
crash once by changing the current directory and then going into the
GUI preferences and changing back to MDI mode. It has not occurred
simply changing directories.

If I can get this to occur with a predictable sequence, I'll post it.

For the record, this is R 1.7.0 under WinXP Pro with all updates.

A thought occurs to me in that I wonder if there is something to the
folder browsing dialog window/tree control and/or perhaps something
related to the change in window focus under SDI mode.

I have not been able to get this to happen if I just go into SDI mode
and then change back to MDI. It does seem in some fashion related to
the use of the folder browser control.

Regards,

Marc Schwartz

For me a crash as well in MDI without having SDI mode used at any time.
