This does sound like a bug, but it’s hard to know. Using different stop codes 
seems like a rational way to approach the problem.

Other possibilities you might investigate:

1. Close the modal window before using the NSOpenPanel, then reopen it with a 
new modal session afterwards.

2. Display the NSOpenPanel as a sheet on the modal window, rather than a 
separate window.

Is Carbon involved here in any way? This code looks like it was Carbon once, at 
least.

runModalSession handling

[Tom Doan]

Based upon a recommendation that I found, I changed up code from running a 
modal dialog to use 
beginModalSessionForWindow and runModalSession. Unfortunately, if I run an 
NSOpenPanel from within this 
(used for a browse for a target directory), runModalSession for *my* dialog 
returns the 0 or 1 off the open panel 
as soon as that closes, thus (with my expected handling) closing my dialog as 
well. I checked and none of my 
stopModalWithCodes are being fired, so the result code has to be coming off the 
system dialog. I did a kludge 
where I used 100 and 101 for my own stop codes, and continued on 0 and 1, and 
that seemed to work around 
this, but I would really like to understand what is wrong with this setup.

Best regards,

Tom Doan
