Rony, I was using 3.2.0 on Windows just the other day and I didn't see any
problems.
If I understand you correctly, it is when you use WSH, that you see
problems and that it is Internet Explorer that crashes. If that is not
correct, then ... well explain to me what I'm not understanding. <grin>
The whole, entire, reason that WSH is disabled in ooRexx 4.0.0 and on is
that it was implemented using undocumented kernel entries that are *completely
unsafe*. Rick would not release 4.0.0 with a feature, WSH, that he knew
was unsafe and was likely to crash. That WSH is not stable and causes
Internet Explorer in Windows 7 to crash, is not a surprise. It is
predictable.
>From what I saw in the code, WSH was not written in a generic way, it was
written in a reactive way. It was written in an approach that said, 'oh,
Internet Explorer sends a 0x7 here sometimes. We'll check for a 0x7 and
then do this...' As soon as Internet explorer changes, that code would
break.
