#2027 text/entry widget in safe interpreter

[Martin]

The following problem occured with tk8.4.13rc0 as well
as with tk8.4.12, but ONLY when running under Windows
(WinXP SP1):
When creating a text or entry widget in a safe
interpreter it is not possible to enter text in these
widgets (not even an input cursor when selecting the
widget).
I used the following script to demonstrate the bug:
set engine [safe::interpCreate]
safe::loadTk $engine
$engine eval {
pack [entry .e] [text .t] [button .b -text "OK"
-command {.t insert end "OK "}]
}

This bug is reproducible in 8.4.19 but is ok in 8.6 HEAD
