FixScalos is a patch for Scalos 1.2d to
 avoid crashes during screenmode changes.

 Scalos 1.2d still tries to release some
 pens of the screens colormap even when
 the Workbench is closing and has already
 removed and freed some data structures.

 This has the bad effect that calling the
 ReleasePen() function leads to accessing
 invalid pointers and reading random data.
 The same happens with GraphicsReserved1().

 In order to avoid the crashes which are
 caused by this incorrect behaviour of
 Scalos 1.2d in conjunction with the v1.3
 iconobject system files this FixScalos
 patch disables the ReleasePen() function
 as long as the Workbench screen is closed.
 It also checks some of the pointers for
 invalid addresses and aborts all function
 calls if the addresses are negative, odd
 or zero.

 Since Scalos 1.2d has simply disabled the
 workbench.library function for updating
 icons which is called WorkbenchPrivate1(),
 I've written an emulation to reinstall it.
 This should fix problems with IconMaster.

 Installation:

 Just copy FixScalos into the C: directory
 of your system and start it with Run from
 the bottom of your startup-sequence like:

 .....

 LoadWB
 Run >NIL: C:FixScalos
 EndCLI
