Hi all, thanks for your replies and Martin, thanks for the email.

After going down what feels like a couple of rather large rabbit holes, I 
finally go the bottom of the issue.

My TaskWindow routines were fine.
The issue was with the command I was passing to Wimp_StartTask.

I was using a flag to generate a log file.  I had not appreciated that the 
flag was log file or task window output.
