Hi Zentara,
Thank you very much for taking the time to reply to my posts. I really appreaciate your help in this regard.

My application is pretty big to be able to discuss here. However, just to give you a gist of the code, I'll discuss some salient features of the application here.

I have a bunch of features/functions that I need to carry out using my application. I've designed the framework of the application to mimic a commercial application similar to what is given here.

As such, I am reusing the space on the right to the maximum extent possible by reusing the canvas for the perl Tk widgets using the packForget to avoid the mess of TopLevel widgets for every feature of the program, while maintaing ease of access for the user thereby keeping it simple. However, I have reserved the use of Top level windows for trivial functions like retrieving the dates,etc.

I have not faced any issues so far with packForget options. It is only for a couple of subroutines where I implement m top level widgets where I feel my code is broken. I will look into your suggestions and implement them. Thank you very much ..!!
