Incompatibilities and possible technical problems:
===========================================================================

1) DPMI server HDPMI32
---------------------
For it's work Bloček needs a memory manager called DPMI server. It can be
provided by the Windows kernel or by external program in case when running from
DOS. The default DPMI server for this case is CWSDPMI which is included in the
distribution archive.
However you can start some alternative DPMI server and Bloček will use it
instead.
One of such popular DPMI servers is HDPMI32 which is included in the HX-DOS
package by Japheth. 
Bloček can certainly work with this server but there is one pitfall. You can set
various parameters of this server by the environment variable HDPMI.
There is a incompatibility between set fifth bit of the HDPMI variable (like
HDPMI=32).
This setting separates parent's and child's memory regions when the parent calls
the child process.
In Bloček is this technique used in the QR code generator and with this setting
it will not work.


2) Mouse driver
---------------
In the initialization Bloček follows the DOS programming recommendation and
before using any mouse function it checks whether the mouse is properly
installed. If not Bloček refuses to run.
Unfortunately, this test can be sometimes misleading and the mouse driver
reports error even if the mouse is usable. It can happen f.e. after crash of
some previous program which uses the mouse.
If it is your case, open the configuration file BLOCEK.CFG and edit the
parameter "ruzne_sys_priznaky = ..." to contain the upper cased letter B
