IDE Build 010501 EE on *** LINUX ***
On Linux, when the mouse pointer is on right-top corner 'X' of a dialog, Tooltip says 'Clicking Left mouse button will kill this window. Clicking Right mouse button will forcibly destroy this window'

Suppose,
In File->New->Classes->Class
say name as 'xyz'
In step 3. Basic class Definition, choose '...' for interfaces
Property Editor: (Identifier[]) opens up
Right click on Right Corner 'X', closes/destroys this dialog
The New From Template wizard does not respond now (beeps when clicking on it)
You can close this dialog by left clicking on right-top corner 'X' or choosing close from the dialogs control menu (from let top).

In the second case :
In File->New->Classes->Class
say name as 'xyz' again
go to step 2 or 3
RIght click on Right-Top corner 'X'
The wizard closes
** The Explorer beeps on click
and user will not be able to gain access to explorer or the main forte frame (this too beeps).
Explorer could not be closed by left click on right-top corner 'x' or thru close in control menu
** IDE will have to be restarted
Right clicking on'X'
