That certainly should be the case.  Unless you use the -eventmodel => 
'both' option on the control, only one of PERLWIN32GUI_OEM and 
PERLWIN32GUI_NEN flags should be set for the control in perlud->dwPlstyle.

I haven't tried this yet, but it seems wrong.  Can you raise a bug 
report and I'll dig further into this one.

Thanks,
