Hi Marius,

I see I was correct to dread the next issue :/

I don't have access to Windows 9X anymore (I've never even 
seen Millenium), so I'm not sure I'm ever gonna fix it :(

popen has known problems on Win9X, but it has worked for me before.

Please write a simple test case using os.popen3 to run that file. 
If it works, there is hope, if not, there're not much I can do about it.

Maybe it's time to drop popen for wxProcess, but I don't want to do that 
before the release (I have enough todos)

Cheers,
Riaan.

Marius,

I think this problem goes back a little way...

Let me clarify that, I can create a wxApp, and run it on ME without any
problems, on all python/wxpython versions, and the current version of Boa=
.

When 0.0.13 was released, I experienced a problem where older application=
s
created with pre .13 Boa would not run because the show;hide;show was
missing from the BoaApp:OnInit function.  The Boa produced code would wor=
k
just fine on W2K or XP(real multitasking).  New applications did not
exhibit the problem, because Boa automagically added the "magic" code to
fix the problem.

Make sure in the OnInit fuction there is a line such as:
self.main.Show();self.main.Hide();self.main.Show()

If this is not the problem, please give us a little more detail or, if yo=
u
don't mind, create a small app, and I'll give it a try.

Hi Kevin,

Thanks for tracking this down!

Could you please test this on Python 2.1, I'm sure this worked
sometime in the past.

More an issue of shells/running external processes than multitasking.

If I recall correctly the wxProcess bug was caused by code trying to
hide the console window for GUI applications (but hiding your main window
instead).

I was very glad to remove this "magic" from the templates after 2.3.3
fixed the problem in wxProcess.

I don't want to add it again, especially not just for win9X which I
don't rate as an development platform at all :(

Ok, I've added it again (with a verbose comment)

Cheers,
Riaan.
