Hiren,

Thanks for trying out the Shrew Soft Client. There is no solution for 
this particular problem that I know of. Providing a work around in the 
Shrew Soft Client should be a trivial matter. I have added this to my 
TODO list and a patch will be included in the next 2.1.0 beta release. I 
will send you a notice when the package is available for testing early 
next week.

Very good problem analysis BTW :)

Thanks again,
