self~logError(0,"Fescue.printer set to:" Fescue.printer "on entry")
if Fescue.printer <> '' then return -- stop multiple entry

parse value default_printer with dp ','.
call SysWinGetPrinters all_printers.
do i = 1 to all_printers.0
parse var all_printers.i pname ','.
if pname == dp then do
aprt.i = pname '(Default)'
ldp = i
end
else aprt.i = pname
end
aprt.0 = all_printers.0
m_title = 'Select A Printer For Fescue Program'
self~logError(0,"Preselected:" aprt.ldp)
dlg = .SingleSelection~new('Make A Selection',m_title,aprt.,ldp, ,4)
wt = dlg~execute
waitmsg~ok
if wt <> '' then do
Tkt.Printer~setText(aprt.wt)
self~logError(0,"UpdatePrinter Selected:" aprt.wt)
Fescue.printer = aprt.wt
end
else
self~logError(0,"UpdatePrinter none selected")
Then if I run the following it works as expected:
/* why doesn't printer selection work? */
waitmsg = .TimedMessage~new("Please wait for the list of printers.", ,
"Getting Printer Names", -1)
waitmsg~execute
default_printer = SysWinGetDefaultPrinter()
parse value default_printer with dp ','.
call SysWinGetPrinters all_printers.
do i = 1 to all_printers.0
parse var all_printers.i pname ','.
if pname == dp then do
aprt.i = pname '(Default)'
ldp = i
end
else aprt.i = pname
end
aprt.0 = all_printers.0
m_title = 'Select A Printer For Fescue Program'
dlg = .SingleSelection~new('Make A Selection',m_title,aprt.,ldp, ,4)
wt = dlg~execute
waitmsg~ok
if wt <> '' then
Say "printer selected = "aprt.wt
else
Say "No printer selected"

I agree there is something else going on, but I am out of ideas
of how to try to find out what!
