> I've bumped into a number of problems and annoyances, some new
> and some old, none worth my time reporting officially (enough elevator

> 1.  The WinNT client GUI install does not install the scheduler

> 2.  WinNT backup client (3.7) GUI does not display path info during a
>     backup.  Fileids are displayed in a "Task List" box, but not path.
>      Previous versions did and this information is sometimes helpful.
>
> 3.  WinNT backup client (3.7) GUI "Backup Report" box does not fit in
>     the standard size backup client window.  All action buttons are
>     not visible. There are no scroll bars.
>
> 4.  WinNT backup client (3.7) GUI has no listing, even fleeting as in
>     previous versions, of actions on individual files. File
>     DMSSCHED.LOG should be used, just as with a scheduled backup.

> 5.  (all platform) backup client (all versions) keeps a tape mounted
>     on (VM server 3.1.2.40, all versions) after a restore ... until
>     the backup client is exited.  Server "Mount Retention" should be
>     honored, starting with the end of a restore action, not end of a
>     client-server session.  That a tape is mounted for a client is not
>     visible at the client, even if s/he were there to take action
>     (many restores are started just before the owner leaves for the day).

> 6.  VM 3.1.2.40 server: I've never had a SELECT from CONTENTS with a

>     I've let various SELECTs run for hours.  The same SELECT without
>     the WHERE starts outputting immediately.  Still fails without
>     aliases.

> 8.  VM 3.1.2.40 server, CMS admin client: on a long-running SELECT
>     (try one as above!), "hx" should end the admin client session.  It
>     does, but the admin client never reads the "hx" so when one tries

>     whatever is stacked (hx in this case).  This is an awful work-around.

> 9.  Same as above. The EMSG setting is turned off and not reset in
>     above case.

> 10. Same as above, except enter "#cp req" instead of hx.  One gets an
>     "interrupted by user" message with nothing else happening. Since
>     nothing is read, nothing else at console may be entered.
>     Work-arounds are (a) "#CP IPL" or (b) use other admin access to
>     cancel the problem admin session.

> 11. Same as above, but another admin access cancels the admin session.
>     The CMS admin client session does end, but with an ugly IUCV

> 11:16:59 ANS8051E IUCV communication error.
> 11:16:59 ANS8064E Communication timeout.  Reissue the command.
