[Wrapper-user] Question about release notes

[<iko...@ax...>]

Hello,
I have a question regarding a fix done in version 3.3.6. In the release notes the fix notes state:

- Fix a potential problem on Windows platforms where a failure to register the control handler was not being logged. If this happened, user logoffs would not be trapped correctly but no other problems would have occurred.

The first sentence seems to imply that there are conditions where the handler cannot be registered and the problem that was fixed was that now that condition is logged whereas before it was not.  The second sentence seems to explain the effects of the handler not being registered correctly but it is not evident from those two sentences that there is now a fix to ensure that the handler is in fact registered correctly.

My questions are, did this above fix ensure that the control handler is registered correctly or are there certain conditions under which the handler would not be registered and how likely it is to occur?  Is it limited to certain circumstances or environments?

Thanks,
Ian Koelliker
