[Oberon] Trapping LinzV4 under Windows XP

Sat Oct 1 04:18:13 CEST 2016

Chris:

  my fresh installation displays the same version number as yours (snippet attached). 
The installation tips seem not very helpful ;-(

On my XP machine the freshly unpacked LinzV4 traps on 
Documents.Open Welcome.Text. Other texts seem to open OK. The Welcome was important 
because I forgot how to use the mouse. It has been a while since I last used V4. 

The trap first opens the Windows alert box (attached).

After dismissing the box the screen shows two traps in the System track
(screen dump attached).

 I managed to print the upper trap using the Edit menu. So the System is basically 
working, except for this strange inability to open Welcome.Text. 

I managed to open Welcome.Text under BlackBox (after renaming to Welcome.Text.eth). 
Even the clocks are ticking in that file under BB. Long live BlackBox. So I can refesh my memory
how to use the mouse. 

However, seeing V4 trap is discouraging. It used to be very robust.

Perhaps I will reboot the machine, what often helps for an unknown 
reason (but I need to finish my current work first). 

Wojtek

Wojtek,

I've got V4.0-2.3 of LinzV4 running on my 64-bit Windows 10 system. The date
of the setup.exe file is 18/12/1998 which corresponds to the date in the ftp
URL that you supplied. Have a look in the README.TXT file that you can
download separately. It has a few tips on how to debug installation
problems.

Chris.
