1. Open PGS.
2. Open Edit/Define/Kerning Pairs. Leave it open.
3. Open Edit/Define/Hyphenation. Leave it open.
4. Close PGS.
5. Open PGS. Well, it will not. Windows comes with a crash error.
Because PGS did not close properly. It still exists in memory. CTRL-ALT-DEL will show this. After closing PGS with this Windows Task manager, PGS will start up as normal!
(It can be done with other requesters as well)

It doesn't have to be two requester windows left open.
Even one left open requester and then closing PGS gives the same result.

Still exists in PGS 5.0.4.34.

Still exists in PGS 5.0.5.8 and Windows 7.

With Pagestream 5.0.5.8 and Mac OS 10.6.8 I cannot carry out steps (3.) or (4.) When the "Define Kerning" pane is open, the EDIT menu is totally ghosted, hence step (3.) is not possible, and furthermore, the menu item <Pagestream -> Quit PageStream> is ghosted and so step (4.) is not possible. Hence, it appears that 5.0.5.8 on Mac 10.6.8 is okay.
