WINE unhandled fault when calling windowdelete from a windowmenu

It seems that calling WindowDelete as the result of a WindowMenu option is causing MUSHclient to crash for me in WINE. It does not crash in Windows 7 doing the same thing, so clearly this is a WINE issue, but maybe there's a way to prevent it from happening?

wine: Unhandled page fault on read access to 0xfffffffe at address 0x4d1057 (thread 0009)

(not urgent, since I have a very handy workaround already)

Is the window deleting itself?

Yup. :)
FYI, my workaround is "don't do that". The nasty part is that it seems to work just fine in Windows.

Luck.

In C++, nothing stops an object from deleting itself, it just isn't a good idea. Same here.

Having to work around this just makes triggering the deletion and recreation of a miniwindow from user events a bit cumbersome and horribly confusing until you realize what's going on.

(My reason for trying is: http://mushclient.com/forum/?id=11045&page=999)

Version 4.73 will now return status eItemInUse if a miniwindow attempts to delete itself.
