Hello,

I forwarded your report last year to the bugzilla.  However, I notice now
that it has vanished and has been replaced by a mantis bug tracker.  

Before I report this again, could you kindly verify it still happens
with the current ipe in testing/unstable (7.0.14)?  I have just tried,
and failed, to reproduce the issue.

Thanks,
-Steve
