Upstream closed the bug based on the patch you sent to the list, which was invalid in the way I describe: https://trac.wxwidgets.org/ticket/18463#comment:4 Independently, I had previously tried to reproduce based on just your description, and was unable to. Maybe there is still a bug here, but if so you really need to provide a valid reduced testcase to demonstrate it: https://trac.wxwidgets.org/wiki/HowToSubmitTicket#ReproducingtheProblem Given such a way to reproduce a bug, upstream have a very good track record for resolving it, but bug reports that require someone to try to reproduce the situation from a description tend to just languish (upstream already have nearly 2000 open tickets, most of which have no clear way to reproduce provided). So if you want to get a wx bug fixed, the key thing is to provide a reduced way to reproduce it, ideally as a patch against one of the samples. Cheers, Olly
