Yes, I found this to be the case on Win XP as well. 
I tested 2.5 with a Windows program, and you could tell right away by
how long it took for the program window to come up compared to 2.4.

I just timed:
   exw ide 
(ide-18), and it took 6 seconds to completely start up.

You mean only the statement
   with trace

without any call of
   trace(1),
   trace(2) or
   trace(3)

in the program? Huuu ...
I think that is worth to be mentioned in the documentation
(couldn't find this info in the docs).

On this occasion I read in 'lib_s_t.htm#trace':
"All forms of trace() are supported in the Public Domain interpreter,
but only for programs up to 300 statements in size. For larger programs
you'll need the Complete Edition interpreter."

But in 'relnotes.htm' it reads:
"The free Public Domain Interpreter (ex.exe, exw.exe, exu), now includes
full support for trace() beyond 300 statements, and for profiling. Thus
there is no longer a registered 'Complete Edition' interpreter."

   Juergen

There is now only one, fully-enabled, interpreter.

Then why did trace(1) in an exu program still come back with an
error?!?
Better make that 2 things to fix, eh?

ok, found the cause, line 558 in winwire, and I added a frame
counter(cause me eyes don't count that well) in 2.4 count=5-fps=90,
500=1100, 2.5 5=90 500=1400, so basically all things
considered(properly) the count change messed me up, but 2.5 is faster
1100vs1400.

Daniel

2.5 is winwire line 558
	for i = 1 to 5 do
	    spin()
	end for
2.4 is winwire line 558
        for i = 1 to 500 do
            spin()
        end for
