Hi
I am using SystemWindow to open a Morph in my application searchQuick. ( https://github.com/jig08/sQuick_new )
On clicking a button, a new screen opens up but the prev window fails to close, though I have tried using #close methods.

The code snippets are as:

------------------------------------------------------------------------------------------------------------------

IndexInterface>>#initialize

. . . . . .

�� boxWindow := SystemWindow new.

�� box position: 150@0.

�� boxWindow addMorph: box.

�� boxWindow extent: World extent.

�� boxWindow openInWindowLabeled: 'searchQuick'.

�� boxWindow fullscreen.

�� boxWindow color: Color black.

. . . . . . .

browseBtn on: #click send: #value to: [self boxWindow window close. IndexInterface delete. BrowseFiles open].

-------------------------------------------------------------------------------------------------------------------

IndexInterface>>#delete

box isNil ifFalse: [ ��self boxWindow window close.��

�� self boxWindow window delete .��

�� self boxWindow close.��

�� box window close .

�� self boxWindow delete.��

�� box delete.].

box := nil.

self boxWindow window close.��

self boxWindow window delete .

self boxWindow close.��

self boxWindow delete.

boxWindow := nil.

-------------------------------------------------------------------------------------------------------------------

Help appreciated.
