To be frank, I'm not overly happy with this. I asked:

"Please supply a short working script."

The code you've supplied does not even compile.

I also asked:

"Also provide verbatim copies of any warning or error messages you're seeing."

So, where is: 

Global symbol "$user_entry_don" requires explicit package name at ...
Execution of ... aborted due to compilation errors.

Would I be right in assuming that you didn't even bother to test this code?

In addition, I asked you to exclude any code that wasn't "relevant to the problem at hand". You've included four modules not used by the code you posted (Getopt::Long, Cwd, List::Util and Tk::ROText), a geometry() call (only suitable for particularly large screens) and other code: all irrelevant!

I changed:

        $dialog_top->Button(-text=>"OK",-command=>sub {$user_entry_don
+e = 1 unless($temp_var =~ m/^$/);})->pack;

[download]

to:

        $dialog_top->Button(-text=>"OK",-command=>sub {$user_entry_don
+e = 1 unless($temp_var =~ m/^$/);})->pack;

[download]

The script now compiles and runs without any error or warning output. The "Test" button pops up the Toplevel; I'm able to enter text from the keyboard in the Entry widget; the "OK" button removes the Toplevel.

I swapped the order of the Entry and Button widget code. Other than those widgets appearing in reverse order, the script runs the same as before.

I am unable to reproduce your problem.

I'm using Perl v5.18.1 and Tk v804.031 — perhaps try upgrading if you're using older versions.
