[fixed] new geometry window

[Hank]

hi there,

W3D 2.2.4
Linux Mint 19

New geometry window crash the program with below result:
Dump written 2019-8-24_19-59
Version: 2.2.4
Window: [wings_frame,wings_frame,<0.91.0>]
Reason: {badmatch,false}

Stack trace:
[{wings_frame,detach_window,3,[{file,"wings_frame.erl"},{line,978}]},
{wings_frame,handle_event,2,[{file,"wings_frame.erl"},{line,344}]},
{wx_object,handle_msg,5,[{file,"wx_object.erl"},{line,468}]},
{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,249}]}]

+ recording:



Just add new geometry window, then unpin it and pin again (few times). Between pin/unpin click LMB in both geometry windows. Sooner or later it will crash.

BR, Hank
