The following works very well for me on Unix server running Solaris.
Example:
open "|Vtext.tcl selcustacct.sql $cust_acct_num &"
Note: The first line in Vtext.tcl is:
#!/apps/devtools/tcl-8.03/bin/wish -f
Note: File permissions for Vtext.tcl were set with:
chmod 775 Vtext.tcl (rwxrwxr_x)
Vtext.tcl runs the shell script selcustacct.sql and displays
the output in a scrollable text wiget with line wraping set to "no wrap"
Hope this helps.

Are you using the exec command?
If so, sounds like you need an & at the end of the command run
in the background. This works for me.
for example:
proc {chatu} {{pt 5000} {id xid}} {
exec wish chat.tcl "$pt" "$id" &
}
