I have no Win95a clients so i don't know if this works.

Just a suggestion:

Try to use the the start program.

Instead of:

code:
Shell 'Program.exe'
Try using:

code:
Shell '%COMSPEC% /C Start /Wait "Program.exe"'
-Erik

ps.
In Win9x Start.exe is a program found in %windir%\Command, in NT+ it is a build in command
