[SM-USERS] Squirrespelll with PHP ISAPI on Windows with IIS problem

[Neil S. <ne...@eo...>]

I have hMailServer 3.4.1 on Windows XP with PHP 4.3.11 and Squirrelmail 
1.4.3a

All works well with PHP server API set to CGI but when PHP server API is 
set to ISAPI I get this error from Squirrelspell

Warning: exec(): Unable to fork [cat.exe 
../../data/bd8a5391598d188df4af0da7fac84949 | 
C:\inetpub\aspell\bin\aspell.exe -a 2>&1] in 
C:\Inetpub\wwwroot\hmail\plugins\squirrelspell\modules\check_me.mod on 
line 107

Warning: join(): Bad arguments. in 
C:\Inetpub\wwwroot\hmail\plugins\squirrelspell\modules\check_me.mod on

SquirrelSpell is misconfigured.
I tried to execute 'C:\inetpub\aspell\bin\aspell.exe -a', but it returned:

Any help would be appricated as I would really like to be running the 
ISAPI API.
